Can a script randomly select an action within a specific set for use on multiple images?

Question

Hi there.
I have a folder of 200+ similar images (taken in a photobooth).
I have made 8 seperate actions within the same set that apply slightly different textures to a image. Actions are titled 1, 2, 3 ...etc.
I am wanting a way to get all the images to have one of the actions (randomly selected) applied to them.
I'm pretty confident that this could be achieved with scripting, but have no idea how to write one.
If the images were sequecnially applied to action 1 then 2 then 3 and so on (repeating when back to 8) this would also be suitable.
I am fairly new to scripting so please keep answers simple where possible,
Many thanks.

Something like this?
// make variable to hold the name of the action set
var actionSet = "myActionSet";
// make variable to hold an array of action names you want to use from that set
var actionArray = ["Action 1","Action 2","Action 3","Action 4","Action 5","Action 6","Action 7","Action 8"];
// either hard code the folder path
// var sourceFolder = new Folder('~/desktop/booth');
// or prompt for folder
var sourceFolder = Folder.selectDialog("Select the booth pix folder");
// if prompting user make sure they didn't cancel the dialog without selecting a folder
if(sourceFolder != null ) {
    // make variable for processed folder
    var processedFolder = new Folder(sourceFolder+'/processed');
    // make sure it exists
    if(!processedFolder.exists) processedFolder.create();
    // get the files from the folder using a mask to only get certain file extensions
    var files = sourceFolder.getFiles(/\.jpg$/i);// here we are only getting jpeg files with .jpg or .JPG extension
    // now loop through the files and apply random action
    for(var f=0;f<files.length;f++){
        // open a file in the files array
        var currentDoc = app.open(files[f]);
        // generate a random number between 0 and 7 ( array index is zero based )
        var rand = Math.floor((8)*Math.random());
        // apply a random action to the opened document
        app.doAction(actionArray[rand], actionSet );
        // make variable for the new file path
        var saveFile = new File(processedFolder+'/'+files[f].name);
        // save the file
        SaveAsJPEG( saveFile, 8, true );
        // close the doc
        currentDoc.close(SaveOptions.DONOTSAVECHANGES);
        // done with this file so loop to next
     }// end of loop
    // done with all the files in the files array
    alert('Done');
}// end of if valid folder
// function to save jpeg
function SaveAsJPEG( inFileName, inQuality, inEmbedICC ) {
var jpegOptions = new JPEGSaveOptions();
jpegOptions.quality = inQuality;
jpegOptions.embedColorProfile = inEmbedICC;
app.activeDocument.saveAs( File( inFileName ), jpegOptions );
