I think you might be looking for pkgpolicy=last in your yum.conf.  From the

              Default:  newest.   Package  sorting  order.   When a package is
              available from multiple servers, newest will  install  the  most
              recent  version of the package found. last will sort the servers
              alphabetically by serverid and install the version of the  pack-
