Actually, it displays pairL in the order of its levels. Trellis for S came 
with a function reorder.factor to re-order the levels, and base R has it 
too.  There is a very similar example on ?reorder.  More generally, see 
?levels

(There are other reorder.factor functions in Hmisc and gdata, which you 
may need to avoid.)
