On the primary BGP session I would set Local-pref 150 and send MED 100 for example. On the backup BGP session, set local-pref 100 and send MED 150.
The local-pref will set the preferred route in your network to use the primary BGP session. The MED should influence the customer to use the primary link as their preferred route as well. Savvy customers can easily override the MED value, but it should work for the majority of the customers.
