I found a stat-priority pawn string here,
Stamina [12.07] > Versatility [9.07] > Haste [7.57] > Mastery [6.07] > Crit [4.57] > Strength [3.07]
what I'm missing though is the armor value. Why isn't it mentioned in the suggestion? What would be the appropriate value for it? An item with an higher armor value / higher item-level makes a huge difference for other tanks like the guardian druid, I heard. Isn't this the same for Prot Paladins?
