Nothing was being transferred from reminders to OF after I upgraded to IOS6. I tried switching it on and off a bunch of times.

Finally, I restarted Omnifocus on the iPhone after turning off the reminders feature (from the home screen, double click the home button. This brings up the list of recently used apps. Press and hold down OF until the icon starts wiggling. Then touch the "-" to close it. Press the home button again.

Then restart OF and go to the Capture Menu to turn reminders on…

You might need to do a similar thing for your list.
