Maybe--although it seems like if you could avoid the shriek so easily, they wouldn't be worth $750 because of the difficulty of digging them up. Personally, I think it's just GURPS trying to bring Myth in line with its own formalized magic system, and the fact that GURPS already has a more traditional kind of mandrake root. I might actually write to their errata page again, as I think it's a genuine error.
