How to resolve multiple monster special (attacks / abilities) on one attack

[CaptSnigs]

I'm going to use an eidolon, because as of yet it's the only way I've found to be able to this so far.

Build an eidolon with trip, grab, and push. When you attack do you get all 3 abilities, and if you do which order do the resolve in? Because if you get all 3 and can decide the order you can do some drastic repositioning assuming everything works. You can trip, then grab with reach, and because of grapple rules you can now place the enemy on the opposite side of you adjacent, then push them towards your team.

Maybe I've misunderstood something regarding the special stuff triggered from an attack, what are your thoughts on this?

The rules do not say, so it would be up to the GM.

Generally the user of multiple triggering abilities should choose the order they apply.

Also you would not get away with moving an enemy around you in any of my games via grappling- that is what reposition is for. Grapple moves the grapplee to the closest open space adjacent to you.

I doubt you can push away an enemy you're grappling, unless you release the grapple.
