1. 13.11 beta v9.5 and 13.12whql are the same
2. All AMD software must be uninstalled before trying to install the 14.1 beta (read the 'read me'), so it is safe to assume if you want to install a earlier version you must remove all instances of the 14.1 beta driver first.
3. 13.12whql has a much talked about bug ..where it shows the version number of the drivers you replaced them with. You can change the version number manually if it bothers you. Search the forum.
