ELI5: Why is it so easy to count down (10, 9, 8, etc.), but so difficult to recite the alphabet backwards?

Because the arrangement of the alphabet is ultimately arbitrary but the arrangement of numbers is not; because of the fact that the arrangement of numbers is meaningful (for example, you probably do subtraction all the time even without noticing) you get good at it; but because you very infrequently need to reverse the (arbitrary) order of the alphabet, you don't get good at it.
