Yes. It is very common that, despite NSDictionary accepting any
object as a key, you must use NSString keys.

Not true. See -[NSString compare:options:] with the NSNumericSearch option.

I would instead suggest subclassing NSDictionaryController and
overriding -arrangedObjects. The naive implementation would call
super's implementation and return a sorted version of the result. The
published interface says that -arrangedObjects returns id, but the
documentation says that it returns an array, so I would feel
reasonably safe treating the return value as an NSArray.
