How can I sort an NSTableColumn of NSStrings ignoring "The " and "A "?

I've got a simple Core Data application that I'm working on to display my movie collection. I'm using an NSTableView, with it's columns bound to attributes of my Core Data store through an NSArrayController object. At this point the columns sort fine(for numeric values) when the column headers are clicked on.

The issue I'm having is with the String sorting, they sort, however it's done in standard string fashion, with Uppercase letters preceding lowercase(i.e. Z before a). In addition to getting the case sorting to work properly, I would like to be able to ignore a prefix of "The " or "A " when sorting the strings.

What is the best way to go about this in Objective-C/Cocoa?
