<a href="https://core.trac.wordpress.org/changeset/34370">[34370]</a> made the order that tabs are returned respect the order they are added, however it broke the respect of priority. By using a ksort instead of a sort, we can restore that default behavior. This adjusts the unit tests so that both order added and priority are tested.

Merges <a href="https://core.trac.wordpress.org/changeset/36089">[36089]</a> to the 4.4 branch.
