貼心的JS控制tag cloud排序方式問題

发现搜狐有一个很贴心的功能,用JS控制tag cloud的排序方式~
但我想请问各位高手,能否改到排序方式,不是用自定的4个css,而是用各tag的引用数目,例如原来的
<li class="tag_popularity_4"><a href="">八一</a></li>
<li class="tag_popularity_4"><a href="">文兴宇</a></li>
改成
<li class="tag_popularity_4" title="43"><a href="">八一</a></li>
<li class="tag_popularity_4" title="41"><a href="">文兴宇</a></li>
然後用title来排序.
烦请解答,谢谢 ><
