Hi Sandy,
This is the rule of the game for OSPF path selection and cannot be changed:
Section 11 of RFC 2328, the order of preference for OSPF routes is:
intra-area routes, O
interarea routes, O IA
external routes type 1, O E1
external routes type 2, O E2
I'm assuming you are running a single OSPF process
