How to maintain page order in load pdf/save pdf

Question

(Photoshop CS6)
I want to apply one and the same action to all pages of a pdf-file. The pages have a systematic error, too dark.
So:
1. load pdf-file
2. select all pages
3. apply action, in my case change level, to all pages
4. save all pages as pdf-file, in the original page order.
Thanks,

You could use this script to save the pdf, as it will reverse the order of the documents....
#target Photoshop
app.bringToFront();
main();
function main(){
if(!documents.length) return;
var win= new Window('dialog');
win.pnl1 = win.add('panel', undefined, undefined, {borderStyle:"black"});
win.g5 = win.pnl1.add('group');
win.g5.alignChildren="center";
win.g5.title = win.g5.add('statictext',undefined,'Save PDF');
win.g5.title.graphics.font = ScriptUI.newFont("Georgia","BOLDITALIC",20);
win.g10 = win.pnl1.add('group');
win.g10.orientation="column";
win.g10.alignment=["left","fill"];
win.g10.st1 = win.g10.add('statictext',undefined,'Please enter file name');
win.g10.st1.helpTip="Do not add the suffix .pdf";
win.g10.et1 = win.g10.add('edittext');
win.g10.et1.preferredSize=[250,20];
win.g10.st2 = win.g10.add('statictext',undefined,'Please select output folder ...');
win.g15 = win.pnl1.add('group');
win.g15.orientation="row";
win.g15.alignment=["left","left"];
win.g15.et1 = win.g15.add('edittext');
win.g15.et1.enabled=false;
win.g15.et1.preferredSize=[250,20];
win.g15.bu1 = win.g15.add('button',undefined,'Browse');
win.g15.bu1.onClick = function() {
  outputFolder = Folder.selectDialog("Please select the output folder");
if(outputFolder !=null){
  win.g15.et1.text =  decodeURI(outputFolder.fsName);
win.g100 = win.pnl1.add('group');
win.g100.orientation="row";
win.g100.bu1 = win.g100.add('button',undefined,'Save PDF');
win.g100.bu1.preferredSize=[165,30];
win.g100.bu2 = win.g100.add('button',undefined,'Cancel');
win.g100.bu2.preferredSize=[165,30];
win.g100.bu1.onClick=function(){
if(win.g10.et1.text == ''){
    alert("No file name has been entered!");
    return;
if(win.g15.et1.text == ''){
    alert("No output folder has been selected!");
    return;
win.close(0);
var Names=[];
for(var a=0;a<documents.length;a++){
    Names.push(decodeURI (documents[a].name));
Names.reverse();
var SaveFile = File(outputFolder + "/" + win.g10.et1.text + ".pdf");
makePDF(Names,SaveFile);
win.show();
function makePDF(Names,SaveFile) {
var desc = new ActionDescriptor();
var list = new ActionList();
for(var z in Names){list.putString( Names[z].toString() );}
desc.putList( charIDToTypeID('flst'), list );
desc.putPath( charIDToTypeID('T   '), new File( SaveFile ) );
desc.putBoolean( stringIDToTypeID('includeAnnotations'), true );
desc.putEnumerated( charIDToTypeID('BckC'), charIDToTypeID('BckC'), charIDToTypeID('Wht ') );
var desc2 = new ActionDescriptor();
desc2.putString( stringIDToTypeID('pdfPresetFilename'), "High Quality Print" );
desc2.putBoolean( stringIDToTypeID('pdfPreserveEditing'), false );
desc2.putInteger( stringIDToTypeID('pdfCompressionType'), 7 );

executeAction( stringIDToTypeID('PDFExport'), desc, DialogModes.NO );
