I don't think random/srandom are superseded. I use them myself for game creation. The game just has one number associated with it, I use that to seed random and I can completely recreate the whole game from that one number.
I use the slightly more complicated initstate version. I see no reason why your method isn't working however. Two things to try. Print the first few randoms right after you seed to prove to yourself that you are seeding. Put a breakpoint on srandom, initstate and setstate to see if another piece of code is stomping yours.
