@Magnus - Ignore my instructions. I have the same problem, and was
planning to write a post about it. Then I thought I had fixed it
yesterday with the solution I described to you, but I think it was just
a fluke. (Maybe the windows just happened to be in the order I wanted.)
I've tried Jan's instructions, and they're working for me.

-> Mod+j -> t1 | t2 | (t3) visible: t1 | t3
-> Mod+Shift+k -> t1 | (t3) | t2 visible: t1 | t3
