It's the rank that Murata has stated he has. I think that's more official than anything. Why are Garou and Boros listed as Dragon or Above if they've never been referred to in series as that then? Why are people like Bakuzan or Geryuganshoop listed as Dragons when the HA themselves never listed them as such then?

Orochi's rank as it is right now is Dragon or Above. Orochi's own profile lists it as such. There's no reason for the Monster Association page to call him a Dragon and not recognize that ranking.
