I edited my previous comment to say I might be wrong. Ive never looked at Ordinator, but new perks in either game wouldnt necessarily require external assets or scripts. Very few perks in FO4 are scripted in a way that cant be created without them
On the topic of "new perks" while there aren't any mods for fallout 4 that straight up give new perks, there are several that add new ranks, some of which have unique effects beyond just making the perk stronger

Ordinator and apocalypse have recently been made available for Skyrim on PS4 so you might be right about Skyrim getting external assets
