From the Facebook Developer Forum:
There is no way at the moment to requests extended permissions through the Registration Plugin so you'll need to request it afterwards.
It goes on to acknowledge that this is a missing feature that should be added at some point.
From what I can find, it looks like the legacy fb:prompt-permission tag would be a great way to ask the user to grant the permission. However, Facebook is in the process of deprecating FBML, so that's probably not a good idea.
The Facebook Authentication documentation explains how to gain the additional permissions using the latest OAuth model. I am still struggling to wrap my head around this myself.

Since you're using Facebook registration I'm assuming you have a database that collects user info. So what you need to do is not rely on Facebook to see which user has registered with your website but instead use the simple login with permissions on first time users and then after they are "connected" to your website check to see if they are in your database or not, if not send them to the Facebook registration plugin page and force them to register. :)
