You can pass a comparison function to Array.prototype.sort

you should be able to do something like

$items = $('li[data-azsort]');
var compareElem = function (a, b) {
  if (a.attr('data-azsort') > b.attr('data-azsort') {
    return 1;
  } else {
   return -1
  }
};
Array.prototype.sort.apply($items, compareElem);
