I hadn't really thought about that, that's a good point. I'm used to sorting by largest alignment first too, probably for the same reason you are. If posed with a decision regarding this I'll probably only change the sorting if it's needed to keep access to the smaller stuff.
Same sorting or not, this is definitely an improvement over keeping it unscaled.
