Different bonus types that turn out to apply to the same roll

[hyphz]

We had a small confusion regarding two Fighter abilities.

Battlefield Surveyor: "You gain a +2 circumstance bonus to Perception checks for initiative."

Incredible Initiative: "you gan a +2 circumstance bonuses to Initiative rolls."

My assumption was that these did not stack, because they are both circumstance bonuses.

However, a player argued that they do stack, because although they are both circumstance bonuses they are bonuses to different things: one is a bonus to Initiative rolls, and the other is a bonus to Perception under certain circumstances. If a given roll comes in both these categories then it is affected by both, not because the bonuses stack, but because the roll is in two categories.

Is this correct?

No. Neither is a bonus to Perception; one is a bonus to Perception checks for init, the other is a bonus to init rolls. Since a check is a roll, these are the same thing (roll for init vs init roll).

No, they are both circumstance bonuses, so they don't stack if they apply to the same roll.
