I've been experimenting ways to address this, and may have an option  
worth testing:

In "Home › Administration › Classification sources" you can specify  
the "Filing Rule" to apply to each Classification Source. A second  
table allows you to specify the "Sorting routine" for each Filing Rule.

I found that by changing the Sorting routine from "generic" to "LCC",  
I got my system to sort properly. You might find this worth testing.
