It picks the rpm in the build tag (the local rpm).

The one in the build tag always wins.  This is consistent with normal 
Koji tag inheritance, which is a depth-first, first-match-wins search. 
Koji never compares NVRs.

If you want to use the version from the external repo, untag any builds 
of that package from the local tag and let the external repo version be 
picked up as the first match.
