Here's my own theory on this. The English adjective order does have some logic to it.

   opinion, size, age, shape, color, origin, material, purpose

The adjective closer to noun tends to describe something more like an 'essence' of the noun. Changing the purpose adjective, eg 'savings account' to 'checking account', is more fundamental than changing other kinds of adjectives. The opinion adjectives are the most superficial and most fickle among them.

I haven't tested this extensively enough. Your thoughts and counterexamples welcomed!
