I think I have figured out what is going here:

"Or does this "proxy" sorting phenomenon only occur when binding a KVC-proxy NSMutableArray to the NSArrayController? I mean that, if one binds directly to the actual "model" NSMutableArray itself, instead of a proxy created via KVC-compliant accessor methods, does the "model" itself get sorted?"

The answer to this, at least in Tiger, appears to be yes.

Sorting behavior, that is whether or not the underlying array is actually sorted or not, depends on whether you have bound the NSArrayController to a KVC-proxy array or not. If you have bound to a KVC-proxy, instead of a actual NSMutableArray instance, the underling array is not sort while the proxy is. Otherwise, the underlying array is sorted, as one would normally expect.
