I'm buildong a basic ported box for my 3 sa 12's, would it be a problem if I put one sub on the top of the box and two on the front? Will the subs being mounted perpendicular like that, (mounted on perpendicular walls) cause any problems?

The port is a U port facing upward, same wall as the single sub if that helps at all

assuming the single sub and port are firing off of the trunk wall and the two remaining subs are firing upwards off of the trunk lid, then no. there shouldn't be any considerable cancellation at all.

I was gonna have the single sub and port firing up, why would it be better for them foring towards the trunk? Its going in a hatchback so I faced the port up for better air flow. It will fit either way, should I flip it?

hatchback? even better. I believe the way you described positioning them is fine.
