I'm having this problem on a new rMBP connected to an Apple extended keyboard. OTOH, control-keypad works just fine on a 2011 iMac connected to an old Apple Pro Keyboard. Both are up to date with OS X 10.8.2. I agree that it would be much easier to control-keypad.

Found my own solution. I reapplied the keyboard shortcuts for higher number spaces using the keypad specifically (instead of the number keys atop the keyboard). After that, everything worked fine.
