My proposal would be to give 0 score for all rebel fleet kills, instead of the normal scoring you get for destroying a ship. Otherwise highscores are just a question of how long you bother to jump around in sector 7 killing rebels (it's not hard to get a ship essentially impervious to the rebel ships).
For clarification, here's a discussion I just had at a thread about highscores:
