How to sort OrderedDict of OrderedDict?

I'm trying to sort OrderedDict in OrderedDict by 'depth' key. Is there any solution to sort that Dictionary ?

OrderedDict([
  (2, OrderedDict([
    ('depth', 0),  
    ('height', 51), 
    ('width', 51),   
    ('id', 100)
  ])), 
  (1, OrderedDict([
    ('depth', 2),  
    ('height', 51), 
    ('width', 51),  
    ('id', 55)
  ])), 
  (0, OrderedDict([
    ('depth', 1),  
    ('height', 51), 
    ('width', 51),  
    ('id', 48)
  ])),
]) 

Sorted dict should look like this:

OrderedDict([
  (2, OrderedDict([
    ('depth', 0),  
    ('height', 51), 
    ('width', 51),   
    ('id', 100)
  ])), 
  (0, OrderedDict([
    ('depth', 1),  
    ('height', 51), 
    ('width', 51),  
    ('id', 48)
  ])),
  (1, OrderedDict([
    ('depth', 2),  
    ('height', 51), 
    ('width', 51),  
    ('id', 55)
  ])), 
]) 

Any idea how to get it?
