You want recommendation or help in troubleshooting?
You can handle that in multiple ways. You can set manually local-preference by using route-map everywhere to make sure that the primary path taken is the primary ISP.
However, as you are in a mpls network (I suppose), you can ask your MPLS provider to use community.
In that case, you will announce (network statements) same network to each peers by tagging the community. Your ISP has, usually, at least 2 communities (1 for primary routes and 1 for backup routes). Then everywhere, you will receive the primary routes coming from primary ISP.
If you don't have any mpls, then best way would be, as said before the local preference and/or as-path prepend.
I won't write any configuration, as a lot of documentations on dual homing are already been built by Cisco. Let me share you some links that could help:
