Illustrator Scripting :: Renaming Layers To Be The Text Inside

I've got an Illustrator CS6 document that has 500+ layers with individual words on them (a word cloud).  I'm needing to animate this in AE.  When I "Release to Layers (Sequence)", all of the layers become Layer 1, Layer 2, etc.  Is there a script that will rename all of those layers to be the text inside them? 
 
i.e. Layer 1 has the word "Pencil" as a sub-layer, editable text.. I need to rename the Top-Layer Layer 1 to "Pencil".  I'm hoping there is a script that can do this so I don't have to manually rename all of the layers.I have found this script:
 
var idoc = app.activeDocument;
var ilayer = idoc.activeLayer;
for (i=0; i<ilayer.layers.length; i++) {
    var isublayer = ilayer.layers[i];
    isublayer.name = isublayer.pageItems[0].name;
}
 
But is doesn't seem to do what I need.
