Sorry, the option is missing.
However, you can easily patch the script to set the random seed.
Please try this:

cp $PHENIX/iotbx/iotbx/command_line/reflection_file_converter.py myrfc.py

Edit myrfc.py and insert these lines between "import sys" and "def run():":

from cctbx.array_family import flex
import random
flex.set_random_seed(0)
random.seed(0)

Then:

  phenix.python myrfc.py ...

with the ... same arguments as before.
