yum package version availability does not work with --enablerepo

I am trying to install a package via Yum on some systems from a repo that is disabled by default on the nodes. I was hoping to do this by passing "--enablerepo=my-test-repo" via the package options.

However, the Yum provider appears to have some package version detection since CHEF-2062 that is not aware of my enabled repo. I think it should be possible to override this version detection logic somehow for this use case.
