I started using AS3's Tween function but noticed some strange behavior every once in awhile. Basically, it freezes before it finishes the tween.
This website seems to offer the solution:

My program requires that the rotation tween works precisely every time. I like to use the functions adobe put in place but this makes me nervous since it has such a big issue.
Should I be using AS3's tween or some external tween like greensock.com's TweenLite?
Which would be more reliable?
Most likely your tween instance is being prematurely garbage-collected, because you don't store a reference to it somewhere. This is a common mistake which you can easily Google for.
Solution: store a reference to Tween instance while it is performing animation to save it from GC.
Follow the link for detailed explanation: AS3 Garbage Collection, the reason your tweens are ending early.
Official article on adobe.com also mention this problem (see note at the bottom of article):
Note: Consider variable scope when using the Tween class. If a tween is created in a function, it is important that the variable's scope exists beyond the function itself. If a tween is stored to a variable of local scope, ActionScript garbage collection removes the tween as the function completes, which will likely be before the tween has even begun.
And here are some links on garbage collecting if you would like to learn more on GC logics.
