Order Layers Alphabetically in Photoshop

layersOrder.js

var layers = activeDocument.layers;
	var layersArray = [];
	var len = layers.length;
	


	// store all layers in an array
	for (var i = 0; i < len; i++) {
		layersArray.push(layers[i]);
	}

	// sort layer top to bottom
	layersArray.sort();

	for (i = 0; i < len; i++) {
		layersArray[i].move(layers[i], ElementPlacement.PLACEBEFORE);
	}

Thank you for sharing this piece of code. I was wondering how natural sort could be implemented? Right now the output looks like this:
1a, 10a, 2b. And I was wondering what could be done to make it 1a, 2b, 10a?
