Just apply this time remapping expression.
You just have to edit the first line to match your number. This is one of those expressions that has to recalculate what's happened on each previous frame, so it might bog down if your comp is fairly long.
nFrames = 10;
seedRandom(index,true);
n = Math.floor(random(nFrames));
f = timeToFrames();
for (i = 0; i < f; i++){
  n += 1 +Math.floor(random(nFrames-1));
  n %= nFrames;
}
framesToTime(n)
