it seems to work correctly for me with pymel 1.0.3, try getting the latest
ie: i can select particles and then
ls(sl=True)
ls(sl=1) also works for me
ls(ls=true) does not
c.r

How can I most easily tell my version? Unfortunately I'm writing this for a 
tool that must be distributed at a studio and it may be a while before we can 
get everyone upgraded.

Seems to work for me too - exact code I used to test:

import pymel.core as pm
part = pm.createNode('particle')
pm.select(part)
pm.ls(sl=1)

to tell the pymel version, you can do:

import pymel
print pymel.__version__

closing this ticket unless someone can confirm this is a problem in 1.0.3 or 
later
