When A/a are explicitly provided to the orders argument, they sometimes can produce issues despite the specification being otherwise correct:
With full weekday names, having either "A" or "a" will result in a failure to parse if "B" instead of "b" is used (similar to #972, but seemingly unrelated)
With abbreviated weekday names, the same as above occurs, plus an "Ab" combination will fail to parse.
While I realize that, in practice, neither "A" nor "a" actually need to be present in the default case, it does seem strange that including them causes such failures.
