I really like the options here. It presents edicts and abilities (challenge bonus, skills, special abilities) for each order. There is a nice mix of powers. Order of the Glaive is a good one for pole arms. Order of the Griffon lets you get a griffon (at 8th level) and so on. Order of the Skull is a nice flavorful one for evil cavaliers. There are also some useful cavalier feats. Everything looks reasonably balanced to me.
