Sort jpgs via file list?

Hmmmm... as far as I can tell, that script is still sorting by attributes, not a list? I would need to sort the files by name in a seemingly random order that exists in simple list format.

If the preserved filenames are in the order you want, you could copy the selected files to another folder and rename then back to the preserved filename IE:

var toFind = new Array();
var txtFile = File.openDialog("Please select the text file","*.txt"); 
txtFile.open('r'); 
while (newLine = txtFile.readln()) {
     if (newLine.length < 2) continue; 
toFind.push(newLine.replace(/^[\s]+|[\s]+$/g, ''));
}
txtFile.close();
var Thumbs = app.document.visibleThumbnails;  
var fileList =[];
for(var a in Thumbs){
var t = new Thumbnail(Thumbs);
var md = t.synchronousMetadata
md.namespace = "http://ns.adobe.com/xap/1.0/mm/" 
var PreservedFileName = md.PreservedFileName;
fileList.push([[Thumbs.spec],[PreservedFileName]]);
}
var thisFolder = app.document.presentationPath;
var outFolder = Folder(thisFolder +"/Working");
if(!outFolder.exist) outFolder.create();
for (var z in toFind){
    for(var v in fileList){
        if(toFind.toString().toLowerCase() == fileList[1].toString().toLowerCase()){
            new Thumbnail(File(fileList[0])).copyTo(outFolder);
            File(outFolder+"/"+File(fileList[0]).name).rename(fileList[1].toString());
            break;
            }
        }
}
