Weird Position[list,form] behavior when used inside of Module.

This works:

Position[A, Min[A]]]

where, A = {5.3, 5.4, 5.2, 5.9}.  the Position function returns ( 3 ).

But this doesn't

Module[{ A, B, RETURN},
             A = Table[ F, {i,{.1, .2, .3, .4}]; (* The function F
returns {5.3, 5.4, 5.2, 5.9} *)
             B = Position[A, Min[A]];
            RETURN = B]

The above module returns, { }.

Is this a bug?
