I have temporarily resolved my problem by overwriting the random function to
call my C++ program and use it's random function, which seems to be...
well... random.
If the seeds were the same, I would expect the results I see, but they're
clearly different.
i've just tried this:
function tr(seed)
math.randomseed( seed )
print ("Seed: "..seed,
math.random(10000),math.random(10000),math.random(10000),math.random(10000))
end
for _,s in ipairs

do
tr(s)
end
and i get:

i guess that your Lua's math.random() is not stock Lua's. if it were,
we should get the same numbers given the same seeds.
can other members try this and see if everybody gets exactly the same
random numbers? this is Kubuntu 9.04 x86_64 with Lua 5.1.4 default
install.
