Did you see Evert's reply to your original question? It was pretty close 
to the mark. Though you had not said anything about the .value 
attributes until now.

Try this:
from operator import attrgetter
vars = [ var1, var2, var3 ]
vars.sort(key=attrgetter('value'))
objSprites = pygame.sprite.OrderedUpdates(*vars)

This will sort the vars list by the value attribute of each list item, 
then pass the list as the parameter list to OrderedUpdates().
