I still don't understand the scoring system I guess. Seems odd to me that the commented solution had size 43 ... but doing extra computation reduced this solution to size 33. (unless JIT is at the level to implicitly convert?)

I agree it's not clear ... but y = ~var(nonzeros(sign(diff(x)))); works for both ascending/descending cases. (The test suite clarifies that ascending is the intended case)
