If you need to add random delays you could try several pipes with different delay and "prob" option of ipfw.
Like
  add 1000 prob 0.2 pipe 1
  add 1010 prob 0.2 pipe 2
  add 1020 prob 0.1 pipe 3
etc...
Then you should take into account that with one_pass=1 probability for a 
packet to match 1010 in that case would be (1.0-0.2)*0.2 and 
to match 1020 (1.0-0.2)*(1.0-0.2)*0.1
