Here is what I am seeing from compiling what I believe to be all 135i Coupe VINs from August 2012 to July 5, 2013
June 29, 2012 to August 29, 2012 256 135i Coupes 80 are P7MFA (135is or M-Sport)
May 4 2013 to July 5, 2013 294 135i Coupes 131 are P7MFA (135is or M-Sport)
I started a thread regarding How Many 135is here?
