Sorting a GuiPopUpMenuCtrl

I would like for the popup to list the items in alphabetical order, which it does after a call to .sort(). But it doesn't reorder them internally (ie, the order in which they were added to the control), so if I want the first item in the list to be the default by using .setSelected( 0 ) it will incorrectly reference the first item added rather than the first item in sorted order. (Hope that makes sense.)

Anybody know of a way to correct this?
