As stated, non-pluralized is the "most-used" term; sometimes the show does say "Miraculouses", so it's not a hard and fast rule that they don't. At any rate, regardless of the origin of the term, and its status as an adjective, it's being used as a noun, and thus should follow standard rules of pluralization in English. As far as their frequent failure to do so in the show, some nouns may behave erratically, such as "pair", which some people prefer not to alter in the plural, while others do; and "fish", which nominally does not change in the plural ("There are plenty of fish in the sea"), but sometimes gets away with doing so ("Joy to the fishes in the deep blue sea...").
