There are over one hundred new script functions, Saiden. (118, specifically)
EDIT: Here's a http://www.gamesas.com/index.php?/topic/1127542-new-script-functions/ of all the new functions.
First off your list is inaccurate and by such a degree that a great deal of those functions are Oblivion Functions and DO NOT EVEN WORK for FO3 or FONV !...
EVERYTHING dealing with horses is old and non-functioning.
EVERYTHING dealing with fire EXCEPT the new block type OnFire are old Oblivion and non-functioning -> Unless they got fixed for FONV specificly.
Enable/DisableLinkPathPoints -> Not new.
Everything dealing with AI and Torches -> not new !
IsShieldOut -> Obviously! not new.
Hell you listed PickIdle as new !?!.... Maybe 1/4 of that list are truly new and they deal with the new functions introduced in FONV -> Casinos, hardcoe, Rep....etc. very few of the functions are useful new outside of the new features introduced with FONV
Seriously SAA new ?....
and TriggerLODApocalypse IS NOT NEW -> how do you think they poofed Megetons LOD when you popped the bomb's cherry ! oh wait it was with TriggerLODApocalypse -> Not New......
honestly, being familar with what your talking about helps.
