Hi,
recently I posted an idea in the exchange forum for adding support of sortable headers in bookmark manager: http://forums.ni.com/t5/LabVIEW-Idea-Exchange/Bookmark-Manager-Sort-by-column/idi-p/3136830
So I started to develop a small addin you only need to place somewhere near your code to get the sorting for Listbox, MCListbox, Tree and Table (Table with [shift]-Click).
For Listbox and MCListbox all seems fine, for Tree sometimes you get a crash (I nutshelled this behaviour to the "Sort Children"-Node and reported it). With Table integrated the stopping of this remote VI seems to be delayed. Don't know why.
I'm not sure if I'm on the right way...

Edit:
Bugfixing:
added wait for Frontpanel not closed -> Rev.156 (now works in LV2014)
added little bit error handling
reworked example
