Optimize objects stacking order for vinyl cutting

Hello,

i am looking for a script for optimizing vinyl cutting speed.

The script should be similar to following , but needs to sort the selected objects by the relative position to page origin and not the height from page origin as it does now

script from Arranging stacking order from top to bottom

//David Entwistle

var thisDoc = activeDocument;

// get selected objects

var selObj = thisDoc.selection;

// count the selected objects

var selObjCount = selObj.length;

// sort selected objects by their height from the page origin

var byProperty = function(prop) {

    return function(a,b) {

        if (typeof a[prop] == "number") {

            return (a[prop] - b[prop]);

        } else {

            return ((a[prop] < b[prop]) ? -1 : ((a[prop] > b[prop]) ? 1 : 0));

        }

    };

};

var symbolsSorted = selObj.sort(byProperty("top"));

// for each object in turn in the ordered selection, BringToFront

for(i = selObjCount; i >0; i--){

          var currObj = symbolsSorted[i-1];

          currObj.zOrder(ZOrderMethod.BRINGTOFRONT);

}

redraw();

alert("Selected Objects Sorted = " + selObjCount);

Any help is welcome
