CS6 AI : set scroll wheel zoom directions

So I use OSX Lion with the default reverse/inverted scrolling. In AI CS5 and PS CS6 I'm used to zooming by holding the opt/alt key while scrolling. Just like in these apps, it's expected when I move my scroll wheel up then the artboard will zoom out, and when I move I scroll down the artboard zooms in.

In Illustrator CS6 , this behaviour is flipped and I can't find any way to set/reverse it. Anyone know? This is killing me.

Thanks!
