Answer 1

according to documentation it needs numeric values. more intelligible:

    var sort_by_name = function(a, b) {
         if(a.innerHTML.toLowerCase() < b.innerHTML.toLowerCase()) return -1;
         if(a.innerHTML.toLowerCase() > b.innerHTML.toLowerCase()) return 1;
         return 0;
    }
