err you pasted it as is? or did you edit it a little bit? You need to change character name & the number values after VOutfitRandomMinTime & VOutfitRandomMaxTime to whatever you want them to be.
I think the default time for random animations was something like between 5 & 20 seconds.
The little script extracts I provided are just for adjusting the random animation delay times & do not make random animations play or anything.
here's a simpler version of the script which automatically gets current character & characters current outfit...
getObject("Game.GameCurrentCharacter.CharacterCurrentOutfit"):setValue(VOutfitRandomMinTime, 2000)
getObject("Game.GameCurrentCharacter.CharacterCurrentOutfit"):setValue(VOutfitRandomMaxTime, 20000)
...I think...
