The problem is, that your code doesn't deal with the cut off that
happens with 360 respectively 0. I did not look close enough at your
code to fully understand it, but i think you should add code that deals
with that scenario.
I remember having a similar problem with one of my stacks, but didn't
get around to solve it.
On a related note, did you look at AE from malte? It doesn't solve this
problem, but has some nice handlers to simplify degree calculations and
movements.
I made an other stack that moves a circle using AE, its linked on the
forum (It has it's own problems though):

There's a trial of AE available:

I am trying to write a game, and I need some of the objects to avoid
other objects. I didn't want to use a complicated pathfinder, so I am
just using Obstacle Avoidance. I have a problem with my script so that
if the moving object has to go around an obstacle and in doing so goes
around the very top of the obstacle (they are all circles), it gets
stuck. The problem is that it uses the angle to the destination and
the angle to the center of the obstacle to compare, and sometimes one
of the angles are > 270 and the other is < 90, and it goes the wrong
direction. I have posted the stack and you can just throw this in the
message box:
go stack URL "http://revcompgeek.googlepages.com/obstacleAvoidance.rev";
Just right click somewhere and the mover will try to go there.
The code that needs to be changed is in the mover graphic, on the line
that says
if obstangle < tangle then
