[Moo] MooTools based sortables capcha for phpBB

[Dr.MOON]

There is sortables capcha mod for phpbb based JQuery (http://
www.phpbb.com/community/viewtopic.php?t=1795925), example of working
mod you can look at http://topsecret.org.ua/ucp.php?mode=register. Is
it possible to convert this mod from JQuery to MooTools?
Look at JQuery code:

     //no conflict jquery
      jQuery.noConflict();
function createdata(listnameobject, column, resultid)
{
        // Let's delete all the current input type="hidden" fields, this is
easier to find out which were changed
        var data = document.getElementById(column);

        if ( data.hasChildNodes() )     {
                while ( data.childNodes.length >= 1 ) {
                        data.removeChild( data.firstChild );
                }
        }

        // Run through all childs
        jQuery.each( listnameobject, function(){

                // We only want the ID of the answer
                var answer = jQuery( this ).attr("id");
                answer = answer.replace(/answer_/g, '');

                // And add a hidden input field
                inputbox = document.createElement("input");
                inputbox.type = 'hidden';
                inputbox.name = column + '[]';
                inputbox.value = answer;
                data.appendChild(inputbox);
        });
}

jQuery(function() {
        // Javascript nubs
        document.getElementById('enable_js').style.display = 'block';

        jQuery("#sortable1, #sortable2").sortable({
                connectWith: '.connectedSortable',
                items: 'li',
                forcePlaceholderSize: true,
                placeholder: 'bg3'

        }).disableSelection();

        jQuery("#sortable1, #sortable2").bind('sortreceive', function(event,
ui) {
                // If the left or right column receive an item, put the child 
nodes
in an array
                var arrSortableListItemsLeft = jQuery( "#sortable1" 
).children();
                var arrSortableListItemsRight = jQuery( "#sortable2" 
).children();

                // And create hidden input fields
                createdata(arrSortableListItemsLeft, 'sortables_options_left',
'#sortables_options_left');
                createdata(arrSortableListItemsRight, 'sortables_options_right',
'#sortables_options_right');
        });
})(jQuery);

I tried to convert this code, but I don't know how to send result of
sortables elements...
Here is beginning of Mootools code:

window.addEvent('domready', function(){
$$('#enable_js').setStyle('display', 'block');
var sb =   new Sortables('#enable_js UL', {
    clone: true,
    revert: true,
    opacity: 0.7,
/* initialization stuff here */
        initialize: function() {

        },
        /* once an item is selected */
        onStart: function(el) {
                el.setStyle('background','#ddd');
                },
        /* when a drag is complete */
        onComplete: function(el) {
                el.setStyle('background','#fff');

                //here must be send module
  });
  });

Any Ideas?
