Why not use the 's' flag in the restore command?  This will do the
same thing but save you a command.  From restore (8):

 s       The next argument identifies which dump file on the
         dump media is to be used by restore.  This is useful
         when the dump media has more than one dump image on
         it and not all of them will be restored.
