extra controllers on objects - need help

I almost finished my tool however this problem gives me hard time and no answer.

I have to check on group of objects if any of them contain any other then standard controllers
on size,move,size - x,y,z axises(different then bezier float, size - bezier scale) and transform position,rotatio, scale.
(ultimately I could limit my searching to any other float controller but best would be to search any other then Bezier Float)
I would be very gratefull for any help. I check already in max help and I can figure this out by my self.
