Also, if we're not talking in-game rolls, there were times when you wanted to roll high on percentiles: rolling for psionics and exceptional strength. Didn't psionic combat use percentile dice and higher was better?
I never saw Basic D&D, and lots of wonky stuff got introduced in modules, so I still think that the essential use of the d20 in the initial AD&D rules was still the same basic 'roll high on a d20 to do well'. People writing modules later just didn't get the memo

I guess my point is that 1e didn't start out being inconsistent in rolling dice, even though it may have ended up that way.
I take the point on rolling for exceptional strength and psionics being a 'roll high' situation with percentages - although you were not trying to beat a value, but set a value, which I feel is just on the side of OK

Cheers
