channel priorities for yum

If yum-plugin-priorities package has been removed from rhel7 is there the equivalent functionality provided? I have noticed now that the rhel-x86_64-server-7 and rhel-x86_64-server-optional-7 behave like they have the highest number (ie. worst) priority when competing against other repos. I got burned when yum selected a package from nux-dextop in preference to a redhat channel.

Is there any way to set a yum priority for a redhat channel? I am on a Satellite subscription if that makes any difference.
