After looking over your OT, I think there are a few minor issues but mainly I'm guessing his/her problem is in his/her spell rotation.
The rotation is generally referred to as the 9696 rotation. The numbers refer to the cooldowns for spells. The 6s are for Shield of Righteousness and the Hammer of the Righteous and the 9s are for Judgements, Consecration, and Holy Shield. The idea is that you alternate between the spells with a 6 cd and the spells with a 9 cooldown to maximize threat. For example, Judge, SoR, HS, HotR, C, SoR, Judge, etc.
I also noticed that he/she was using Seal of Righteousness on a boss, which is not optimal. I'd recommend using Seal of Corruption on bosses as it will generate the most threat over time. Seal of Righteousness is better on trash because mobs don't live long enough for SoC to generate much threat. It also didn't appear like he/she was judging very often (9 times during the fight) so I'd recommend practicing the rotation.
In order to minimize wasted talent points and simplify the rotation, I would drop a point out of improved judgements. With the proper rotation, 2 points in improved judgments is a waste because a faster seals would break the rotation. I'd suggest putting the point into Improved Kings. It's best to max out Improved Kings unless you have a dedicated paladin that can do it. Of course, after 3.1 that becomes a moot point.
I'd also recommend against the Glyph of Consecration and recommend using the Glyph of Seal of Vengeance. The Glyph of Corruption would again break the rotation and the Glyph of Seal of Vengeance will give your OT 10 expertise when using Seal of Corruption. More expertise means more hits and therefore more threat. I can't tell what glyphs he/she is using so I thought I'd throw that out there.
The other obvious thing would be that your OT should either do the pull or have a misdirect. If he/she still has problems, I'd ask dps to wait a few seconds before they start attacking.
