It doesn't really work like that tbh. I could be wrong, but from what I remember, the codes are assigned in pre-production, after that, it doesn't really matter. A good example, because of the small sample, is the Hamedori series that MOODYZ started this year: the third release wasn't 003, it was 007. Also, it has 14 titles and no 012.
Not even MUTEKI has a sequential line of codes, I think they even have "missing" codes.
