Honestly it sounds more like OCPD to me, rather than OCD. That's pretty much the difference between the two - one is a personality disorder, whereas the other is an impulse control disorder. If you get pleasure out of your obsessions and compulsions - most likely your obsession with a certain routine/way of doing things - then it's probably more OCPD. With OCD you may feel compelled to do/think something, or you may obsess over something, but it causes distress rather than pleasure. That's just my thought.
