AS glyph is indeed more single-target threat than Judgement, if you want to deal with the more complicated rotation and are okay with changing your AS to single-target-only.
SoV glyph will be a top choice assuming it's actually 10 expertise and not 10 rating.
Righteous Defense glyph will, along with all the other taunt resist glyphs that other tanks get, be assumed for raid content. You won't get by without it unless you enjoy randomly wiping. Yes, there are taunting encounters even in Naxx.
So it looks to me like at 80, the Judgement glyph would be the choice of someone who wasn't comfortable with AS or didn't feel they needed RD.
Ugh. WTB SBV Glyph PST
[Edit] I notice you already discuss the glyphs, FWIW I have in fact run some numbers and AS always beats Judgement in terms of raw single-target TPS when used properly.
