You should:
1. Use DIFFERENT in- and out-filters for the peer1 and peer2
2. Add a rule in peer2 in-filter lowering local-preference (for example - to 50)
3. Add a rule in peer2 out-filter setting bgp-prepending (or, if the AS doesn't accept the prepending, a special community that is accepted by the operator)
(edit: ach, now I see that the peers belong to the same AS... Then you can try setting a MED in out-filter for peer2)

If you have 2 BGP sessions and you want to be the administrator and manage them - it would be nice to get some knowledge about BGP :).

I found this really helpful. It explains how to manipulate BGP based traffic:
