It's actually a I-III-II-VI progression in the key of G. Sorry, but I'm not sure on how to work A major into a progression in the key of B.
Tell me, who is this?

What are you doing here?
I'm off to the cupboard, where I keep the bodies...

Okay, I've found out how to work an A major into a chord progression in the key of B.

Here it is:

Bmajor - Eminor - Dmajor - Amajor - Bmajor

This is a I - IVm - b3 - b7 - I progression.

Hope this helps.
