I'm pretty sure Chaotic Commands actually doesn't protect against fear. That's like its glaring weakness, but it's shored up by a low level cleric spell anyway so it's not that big a deal.
@Chronicler: Interesting. I guess I always assumed it protected against any mind related effect. The description "renders the target creature immune to magical commands" is quite open and ambiguous. So do you know exactly what it protects from? "Magical commands" can be interpreted in many ways...
