The "problem" is that you have outer=T.   This is a bug in mtext() - it
basically ignores the setting of las.  I'm looking at some fixes to mtext()
and will include a change for this.  In the meantime, you might be able to
use mtext(..., outer=F, line=par("mar")[4], ...) to fake text in the outer
margin.  For example, try ...

plot(1:10)
box("inner", lty="dashed")
mtext(0:7, side=3, line=0:7)
