Indeed I guess that this is due to the random seed used by LuaTeX: is it
possible to force a new random seed upon each typesetting?
The randomseed is set by context, and saved between consecutive runs of
the same file. Normally, this is what you would want: just imagine what
happens if each of the luatex runs in a 'context' call used a different
value always.
However (this is mostly for Hans), there is a bug in that process: all
randomseeds in mkiv appear to be between 0 and 1. Since
math.randomseed() expects an integer, this gives almost no
randomness at all to the seed values.
If you want near-random randomness, you can set the seed yourself
based on the return value of os.time():
\ctxlua{math.randomseed(os.time())}
Best wishes,
