Mick,

(ccing back to the list as well)

This brute-force method works for me--I double-click a "ctpx" file and 
the test app launches and then displays a messagebox with the name of 
the launched file:

----
import sys
import time
from Tkinter import *
import tkMessageBox

def doOpenFile(*args):
     for arg in args:
         tkMessageBox._show(message=str(arg), type="ok", 
icon=tkMessageBox.WARNING)

tk = Tk()
fr=Frame(tk, height=400, width=400, bg="red")
fr.pack()
time.sleep(2)
tk.createcommand("::tk::mac::OpenDocument", doOpenFile)
for idx, value in enumerate(sys.argv):
     print idx, value
doOpenFile(sys.argv[1])
tk.mainloop()
----

I'm not sure if this works because you set argv_emulation in py2app's 
options, since I don't structure my apps this way, and obviously the 
hard command of "doOpenFile(sys.argv[1])" needs to be wrapped in some 
sort of try statement to guard against the app being launched without a 
file argument, but clearly what you want to do can be done. The opendoc 
event is still useful for dragging the file to the app icon in the Dock, 
regardless.
