They usually have 13, but have recently decided to add a 14th. My guess is they are probably at around 9 or 10 as of tonights.

There's so much going on in the current season of 'Sons of Anarchy' that some fans have wondered whether the show would be able to wrap everything up in 13 episodes.
The good news is, 'SOA' won't have to tie everything up in that time span. FX executives have decided to give the fourth season an extra episode; the season will now consist a total of 14 hours.
"Creatively, this has been Sons' best and biggest season ever," Nick Grad, the network's executive vice president of original programming, said in a press release. The show's creator "Kurt [Sutter] asked us to consider adding an extra episode to fully close this current chapter of the Sons saga. By adding the extra episode, it wraps up a magnificent season in extraordinary fashion. This is a real bonus for fans of the series."
Given that the 'Sons' fourth-season saga will get another hour, the season finale will now air on Dec. 6, instead of Nov. 29. There's no word yet on whether the finale will be 90 minutes long, as some 'SOA' finales have been in the past.
