Invoking -setSortDescriptors: on the array controller does sort it (or should). Back on 10.4, it may have been necessary to follow that with a call to -rearrangeObjects. (And -setAutomaticallyRearrangesObjects: is a method on NSArrayController, not NSTableView. And I don't think it should be necessary to get the array controller to rearrange its objects due to an explicit request like -setSortDescriptors: -- it already knows how to do that. It's a way to make the array controller track the properties of the objects in the array which are referenced by the sort descriptors and filtering predicate so that it re-sorts or re-filters when those values change.)
