Randomize Inheritance Morph Motion Object

 you need these :
 import  math, random
 
 you could set up the shuffle like this :
 def dotheshuffle(array,seedvalue):
 	random.seed(seedvalue)
 	random.shuffle(array)
 	return array
 
 here you actually do the shuffle :
 marrshuffled = dotheshuffleshuffle(marr, seedvalue)
 
 And finally, right before setting the Array you do the switch :
  marr[i] = marrshuffled[i]

import c4d
from c4d.modules import mograph as mo
import math, random
def dotheshuffle(array,seedvalue):
	random.seed(seedvalue)
	random.shuffle(array)
	return array
def main():
	seedvalue=1
	md = mo.GeGetMoData(op)
	if md==None: return False
	cnt = md.GetCount()
	marr = md.GetArray(c4d.MODATA_MATRIX)
		
	marrshuffled = dotheshuffleshuffle(marr, seedvalue)
	marr[i] = marrshuffled[i]
	md.SetArray(c4d.MODATA_MATRIX, marr, True)
	return True
 

import c4d
from c4d.modules import  mograph as mo
import  math, random
# re compile everytime you change the scene
def my_shuffle(array,seedvalue):
		random.seed(seedvalue)
		random.shuffle(array)
		return array
def main():
	seedvalue = 1
	md = mo.GeGetMoData(op)
	if md==None: return False
	cnt = md.GetCount()
	marr = md.GetArray(c4d.MODATA_MATRIX)
	fall = md.GetFalloffs()
	global marr1
	try:
		marr = marr1
	except NameError:
		pass
   
	frame = doc.GetTime().GetFrame(doc.GetFps()) 
	
	if frame==0:
		marr1 = my_shuffle(marr, seedvalue)
	for i in reversed(xrange(0, cnt)):
		marr[i].off = marr[i].off
	md.SetArray(c4d.MODATA_MATRIX, marr, True)
	return True
