I've seen both guns spelled both ways when doing a bit of research. Given the context of the assault pistol ban, it's infinitely more likely that it was referring to the Intratec version, which is a .22LR clone of the TEC-9.
Not just that, the Czech gun has that Caron mark above the "Š" in Škorpion the Skorpion in the MD code does not have the mark above the "S".
