Hello,

No, I am afraid this is not possible (as simple as it sounds) for techinical reasons/scaleability. It has to do with the way the profile information is stored in the database and how it is retrieved. You could modify the source and use a grid control and do non-server side sorting (as in, sort the data you have, but this is not true sorting as it is only sorting the record set you are dealing with).

I'm afraid I don't have the time to work on customizations like this - there is the option of a sponsored enhancement which is were I work at an hourly rate and build the enhancement into the next version (so it is not a customisation). I have a few of these lined up though, so it may be easier for you to give the source to another developer to customize.
