I don't think they would have to mess with the scales at all if they would just do one other thing....

Make the good (lucky) events as desirable as the bad (unlucky) events are undesirable. In this way, taking order to reduce the frequency of events could prove costly. Taking unluck would cheat your empire of the very amazing things that could happen if you were lucky.

Just changing the random events could make balanced luck and order scales as desirable as order 3, unluck 3, which is my current favorite.
