I guess it's a timing issue. Ignore that iTunes is switching to focus and hold down power and home for ten seconds. After you release power make sure you are still holding the home button for another 10 seconds. You know it works if Pwnage switches back to the foreground.
And if you really want to do this with Pwnage's own timer you can close iTunes and kill "iTunes Helper" (use the app Activity Monitor to do so - if you don't use OSX in English you might have to search for it). That way iTunes doesn't start when you plug in the iPhone. But after Pwnage has build the custom firmware you'll have to start it manually.

I've got my custom restore file made, waiting for me on my desktop, but I cannot get the phone into DFU Mode. If the "connect to iTunes" logo is on, i get an error (6), if the screen is blank, i get an error 1600
