There's a Top Profiles module at the old Mambojoe site in the downloads section. See
www.mambojoe.com/component/option,com_remository/Itemid,27/func,selectcat/cat,2/
This won't let you sort any particular list...I think it's just the most viewed profiles. You can set it to return 4,5,6 or whatever number of profiles you want.
Of course, it's kind of a self fulfilling prophecy, since the people shown get more and more hits.
