I hope that was just a mistake, and they should be "item" bonuses.
Also, in the Figurines of Wondrous Power, I saw something a bit alarming. When you have conjured a creature, you must spend a minor action to direct it to perform an action (whether standard, move, or minor). It is also limited to the normal amount of actions (one standard, one move, one minor). So, if you want it to move and attack, you spend two minor actions (one for move, one for attack). However, if it is a mount, it acts as if you have Mounted Combat and if you are riding it, you can direct it as a free action, which means that it gets it's full set of actions at the same time you do... in addition to the Mounted Combat bonus.
So, if it's just a conjured creature, you get a total of 3 actions divided between the two of you. However, if it's a mount, you each get all 3 of your actions (total of 6 actions) as well as the Mounted Combat bonus. That just strikes me as wrong.
