Batch Crop & Straighten

Question

A while ago a good chap helped me out by creating a script that prompted the user for a folder, then ran the Crop and Straighten Photos command on all images contained in the folder and saved the newly created photos in a new folder.  The script is below.
The script saves cropped photos as PNGs, I'd like to save them as JPEG.  Could someone help me out by tweaking the script to save as JPEG?  I'd like them saved with the highest quality option.
#target Photoshop
app.bringToFront;
var inFolder = Folder.selectDialog("Please select folder to process");
if(inFolder != null){
     var fileList = inFolder.getFiles(/\.(jpg|tif|png|)$/i);
     var outfolder = new Folder(decodeURI(inFolder) + "/Edited");
     if (outfolder.exists == false) outfolder.create();
     for(var a = 0 ;a < fileList.length; a++){
          if(fileList[a] instanceof File){
               var doc= open(fileList[a]);
               doc.flatten();
               var docname = fileList[a].name.slice(0,-4);
               CropStraighten();
               doc.close(SaveOptions.DONOTSAVECHANGES);
               var count = 1;
               while(app.documents.length){
                    var saveFile = new File(decodeURI(outfolder) + "/" + docname +"#"+ zeroPad(count,3) + ".png");
                    SavePNG(saveFile);
                    activeDocument.close(SaveOptions.DONOTSAVECHANGES) ;
                    count++;
function CropStraighten() {
     function cTID(s) { return app.charIDToTypeID(s); };
     function sTID(s) { return app.stringIDToTypeID(s); };
     executeAction( sTID('CropPhotosAuto0001'), undefined, DialogModes.NO );
function SavePNG(saveFile){
    pngSaveOptions = new PNGSaveOptions();
    pngSaveOptions.embedColorProfile = true;
    pngSaveOptions.formatOptions = FormatOptions.STANDARDBASELINE;
    pngSaveOptions.matte = MatteType.NONE;
    pngSaveOptions.quality = 1;
     pngSaveOptions.PNG8 = false; //24 bit PNG
    pngSaveOptions.transparency = true;
     activeDocument.saveAs(saveFile, pngSaveOptions, true, Extension.LOWERCASE);
function zeroPad(n, s) {
     n = n.toString();
     while (n.length < s) n = '0' + n;
     return n;

What a great script. I extended it to recurse through subdirectories, and to filter out images that are too small to be reasonable crops. I hope this helps someone else as much as the original helped me.
#target Photoshop
// This script recurses through a directory structure and saves straightened/cropped images to// a "StraightenedAndCropped" subfolder.// The function that does this tends to produce a lot of junk, so // this script also filters out images that aren't large enough to// be likely candidates.
// optional (for debugging)//$.level = 2//$.bp()
app.bringToFront;// you can use a folder selection dialogvar inFolder = Folder.selectDialog("Please select top-level folder to process");// or you can hard-code the folder if you like (making sure to escape the path in Windows)//var inFolder = new Folder("C:\\some\\folder");if(inFolder != null){    ProcessFolder(inFolder);};
function ProcessFolder(folder) {    // process any files here first    var fileList = folder.getFiles(/\.(jpg|tif|psd|)$/i);
    if (fileList.length > 0) {        // only create a subfolder etc. if we found anything        var outfolder = new Folder(decodeURI(folder) + "/StraightenedAndCropped");        // not sure whether the exists property refreshes on-demand so save an indicator of whether we created the folder        var created = false;        //if (outfolder.exists == false) outfolder.create();        for(var a = 0 ;a < fileList.length; a++){            if(fileList[a] instanceof File){                var doc= open(fileList[a]);                doc.flatten();                var docname = fileList[a].name.slice(0,-4);                CropStraighten();                var originalWidth = doc.width;                var originalHeight = doc.height;                doc.close(SaveOptions.DONOTSAVECHANGES);                var count = 1;                while(app.documents.length){                    // if the width and  height of the derived image are not both at least 85% of both of the original dimensions,                    // do not save it at all                    if (activeDocument.width.value >= (originalWidth.value * .85)                    && activeDocument.height.value >= (originalHeight.value * .85)) {                        // create the output folder on demand                        if ((outfolder.exists == false) && !created) {                            outfolder.create();                            created = true;                        }                        var saveFile = new File(decodeURI(outfolder) + "/" + docname +"#"+ zeroPad(count,3) + ".jpg");                        SaveJPEG(saveFile, 12);                        count++;                    }                    activeDocument.close(SaveOptions.DONOTSAVECHANGES) ;                }            }        }    }
    // now go looking for new folders, and recurse into them (just don't recurse into our own folders)    var fileAndFolderList = folder.getFiles();    for (var i = 0; i < fileAndFolderList.length; i++){        if (fileAndFolderList[i] instanceof Folder && !endsWith(decodeURI(fileAndFolderList[i]), "StraightenedAndCropped")) {            ProcessFolder(fileAndFolderList[i]);        }    }};
// borrowed from http://stackoverflow.com/questions/280634/endswith-in-javascriptfunction endsWith(str, suffix) {    return str.indexOf(suffix, str.length - suffix.length) !== -1;}
function CropStraighten() {    executeAction( stringIDToTypeID('CropPhotosAuto0001'), undefined, DialogModes.NO );};
function SaveJPEG(saveFile, jpegQuality){    jpgSaveOptions = new JPEGSaveOptions();    jpgSaveOptions.embedColorProfile = true;    jpgSaveOptions.formatOptions = FormatOptions.STANDARDBASELINE;    jpgSaveOptions.matte = MatteType.NONE;    jpgSaveOptions.quality = jpegQuality;    activeDocument.saveAs(saveFile, jpgSaveOptions, true,Extension.LOWERCASE);}
function zeroPad(n, s) {    n = n.toString();    while (n.length < s) n = '0' + n;    return n;};
