All the gold class items show up with item level 88 stats in the plugin Compendium, implying that they all scale. Down to lvl 50, I hear, along with the teals, if that instance can be scaled down to 50.
I've personally seen a Malledhrim Captain Shield and a Revered Warden's Earring at sub-85 levels. Earring dropped from like Fear or something at 65, while we were just rushing through it to get Disease/Poison locks for alts.
