Seal of Command should hit each target that Divine Storm does. It shouldn't cleave when applied by Divine Storm, but it should still hit each of the 4 targets. There are a few sources that cite this.

I tested this yesterday when fixing up the guide, on target dummies. Consistently 2 dummies hit by Divine Storm, many times. Each time, only one of the dummies were hit by the seal.
If my Ret Paladin weren't Draenei, I would need to gem some hit, or pick up a hit item somewhere. Did a ICC25hc yesterday and there were only 2 Draenei in the raid (go figure). Without that racial in my current setup, I would be under-hit.
Anyway, those BiS lists are taken straight from EJ. You can check the link for EJ that is near the top of the guide. Now I'm not saying everything in it is perfect, which is why I encourage the use of RAWR to simulate gear DPS rankings depending on what a person has.
