When looking at a Model, the Instance Properties aren't in the right order

(Bug, Closed -> Fixed, Priority: High, Test Status: No automated tests yet , Reported By Justin du Coeur, )
Summary: The Instance Properties should show in the same order as in the Editors -- that is, according to the Instance Props list. Instead, they're showing in alpha order.
I'm calling this a design bug; it's clearly wrong.
Did this ever work?
