Is the Dock written in Cocoa? If so, it must be doing something to
communicate with the Finder to indicate a delete.

The problem is that if I drag a file from the Finder, the Finder does

I believe this is because the Carbon drag manager uses a somewhat
different paradigm when it comes to deleting files. There isn't
really a separate "delete" operation, but it is instead treated as a
file move, but applications are supposed to check to see if the file
(or other object) is being moved to the trash, and if it is, act
appropriately. The trash can in the dock will return the trash folder
as the drop location and the Finder responds by moving the dragged
files to the trash. Unfortunately, there doesn't appear to be any
mechanism in Cocoa to do this.
That being said, I think you should think twice about creating an
exact duplicate of a standard interface element such as the trash can,
unless you're making some sort of dock replacement or something along
those lines.
