I believe that if the keys were valid python identifiers you could access
them using dot notation. E.g.; if a_dict is dict(a=dict(aa='foo')), then
in the template you could say {{ a_dict.a.aa }}. This may work with the
simple numbers, but with the keys containing minuses there may be
problems. You could try quoting them.
If none of that stuff is going to work for you, you aught to be able to
write a simple template filter that filters the dict, and takes the key as
a quoted fight hand argument. You then cascade this for nested
dictionaries.
But if it were me, I'd probably see if I couldn't do it in the view,
producing lists or tuples with the stuff in the order you need them.
