Fighter (Archer): Trick Shot (Sunder) and Manyshot

If an Archer uses their Trick Shot ability to sunder an item, and has Manyshot, what happens?

Does it count as two Sunders with one CMB check? Is it two Sunders and they have to roll for the second arrow? Can these two things even be used together?

My guess is as follows:

The Archer uses the full-round action to full attack. Then he proceeds to use his first ranged attack to sunder the item, using Manyshot.

The attack shoots 2 arrows and provokes (if he has no Safe Shot and Improved Sunder).

He then checks if his CMB-4+d20 >= item's wielder's CMD.

On (true) he rolls damage twice, separately for each arrow.
On (false) proceeds on his attack routine.

That's how I would play it.

Considering Trick Shot can be anywhere within 30', I'd hope the archer is nowhere close enough to anyone to take an AoO. :P

Otherwise yeah, this sounds legit. Granted, you could say something about the wording of Manyshot's wording of "When you make a full attack with a bow, your first attack fires two arrows" and that a sunder attempt is a combat maneuver check and not an attack, but that'd be some rough semantics.
