Feature Manager Design Tree

As far as I am aware, sorting the feature tree is not currently available.

You can, however, drag & drop by hand.

You can vote for SPR#542276 to add this to SW.

Here's a macro I wrote that dissolves any sub assemblies into individual part files and then sorts all of the parts alphabetically.  You can modify it to get what you need.  Also, as with all macros, use at your own risk!  ( Back up your files first, etc....)

It should at least get you goin on the right track.

Good luck!
