Bridge script to automate "open files as layers in photoshop"?

Philip, thanks for your answer. I am a complete newbie, so I write exactly what I did:

1.) I´m on windows 7 64-bit with adobe Master Collection CS6.

2.) I have loaded the following script using copy + past into the ExtendScript Toolkit (CS6):

var stacks = app.document.stacks;
var stackCount = stacks.length;
for(var s = 0;s<stackCount;s++){
      var stackFiles = getStackFiles( stacks[s] );
      if(stackFiles.length> 1){
           var bt = new BridgeTalk;
           bt.target = "photoshop";
           var myScript = ("var ftn = " + psRemote.toSource() + "; ftn("+stackFiles.toSource()+");");
           bt.body = myScript;
           bt.send(5);
      }
}
function getStackFiles( stack ){
      var files = new Array();
      for( var f = 0; f<stack.thumbnails.length;f++){
           files.push(stack.thumbnails[f].spec);
      }
      return files;
};
function psRemote(stackFiles){
app.bringToFront();
var thisDoc = open(File(stackFiles[0]));
var Name = decodeURI(app.activeDocument.name).slice(0,-4);
thisDoc.layers[0].name = decodeURI(Name);
for(var a = 1;a<stackFiles.length;a++){
    open(File(stackFiles[a]));
    Name = decodeURI(app.activeDocument.name).slice(0,-4);
    activeDocument.activeLayer.duplicate(thisDoc);
    app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
    thisDoc.layers[0].name = Name;
    }
      var saveFile = new File('~/desktop/'+(new Date().getTime().toString())+'.psd');
      app.activeDocument.saveAs(saveFile);
      app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
}


3.)  In the toolkit I start the script (with target application Bridge CS6-64 bit): Everything works as expected.

4.) Then I save the script as a "stack-batch.jsx" in the folder "C: \ Users \ kai \ AppData \ Roaming \ Adobe \ Bridge CS6 \ Startup Scripts \ Stack Batch.jsx"

5.) At the start of Bridge I get the Following Following error message:

"Error in C: \ Users \ ... \ AppData \ Roaming \ Adobe \ Bridge CS6 \ Startup
Scripts \ stack Batch.jsx
Line 1: var = app.document.stacks stacks;
undefined is not an object "

6.) Bridge and then starts the script is not enabled.

Thanks for a hint what I'm doing wrong ... Or what might not be right in the script!

Ahh .. this looks great! Huge thank you!
I must admit that I am not a web developer but a photographer (who likes to fiddle). So sorry for my ignorance :-)

Philip, unfortunately, I still see an error in the script:

I run the script within Bridge on a folder with 10 image stacks (4 stacks consist of 5 shots, 6 stacks of 7 shots). But unfortunately, the script sometimes processed 6 stacks, other times 7 stacks (as saved psd files) ... And ends without any further error message. So i end up with just a part of the existing Stacks :-(

Do you have any idea what could be the reason?
