sorting

I'm in a situation where I must output a quite large list of objects by a CharField used to store street addresses.

My problem is, that obviously the data is ordered by ASCII codes since it's a Charfield, with the predictable results .. it sort the numbers like this;

1, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 2, 20, 21....

Now the obvious step would be to change the Charfield the proper field type (IntegerField let's say), however it cannot work since some address might have apartments .. like "128A".

I really don't know how I can order this properly ..
