Use POSITION AUTO on you LABEL definition might help, but you might have 
better luck if you only have two layers colliding by setting

POSITION UC
OFFSET 0 -10

on one layer an then:

POSITION LC
OFFSET 0 10

on the second layer. This will raise the first label and lower the 
second label.


label1
   +      <-- label point
label2


For labels outside the polygon or to avoid collision with other labels 
by using a leader line look at:
