Forcing a tween to spin in another direction?

programming flash
1

I created this flair thing, and I want it to open up in a circle. The problem is that half of them wants to turn in the wrong direction.

Since this is a non actionscript tween I can’t think of anyway to fix it :S and I didn’t find anything on google either. But I didn’t know exactly what to search for either.
