Random Delete tool with Scriptographer

Question

Hi, I am trying to refine the RandomTools created for Scriptographer so that it suits my preference, but I can't figure it out in Javascript. Not knowing a lot of Javascript don't help me either!
Here is the script, simplified to conserv only the Delete part. What I would like to do is to enter a percentage, and then this would be the percentage of selected object removed.
If anyone would point me to a direction with that, It would be really great.

*          this script uses stuff borrowed from keegan's "rando-color.js"
*          as well as from some other things i had written in processing
script.coordinateSystem = 'bottom-up';
script.angleUnits = 'radians';
var sel;
var values = {
          b_delete: true,
          val_deleteAmt: 2,
// gui components
var components = {
          b_delete: {
                    onChange: function(value) {
                              components.val_deleteAmt.enabled = value;
          val_deleteAmt: {
                    type: 'number',
                    fullSize: true,
                    enabled: true
          deleteRule: {
                    type: 'ruler',
                    fullSize: true,
          submit: {
                    type: 'button',
                    value: 'Apply',
                    onClick: function() {
                              Main();
// Setup
function Setup() {
          // initialize the palette window
          var palette = new Palette('Random Delete 0.5', components, values);
// Update
function Update() {
// Main
function Main() {
          // document properties
          sel = activeDocument.getItems( { type: Item, selected: true } );
          //adjust delete range values based on selection number
          components.val_deleteAmt.range = [0, sel.length-1];
          // loop through selected items
          for ( i in sel ) {
                    var object = sel[i];
                    if( object.isValid() ) {
                              // delete
                              if ( values.b_delete ) {
                                        rand = parseInt( Math.random()*values.val_deleteAmt );
                                        if (rand == 0) object.remove();
                    } //end isValid()
} //end Main()
// methods
function random(minr, maxr) {
          return minr + Math.random() * (maxr - minr);
// execution
Setup();
Update();
Thanks

I will do that, but I don't know if the community is still very active there…
And here is the file, if someone want to give it a try!
Right now, the script will delete a random number of items, depending of the number you give in the dialog box, and the number is somehow in relation with the quantity of items selected.
I would like it to delete a given percentage of the items, no matter how much are selected.
