The typical reason for having missing letters or numbers in a sequence is to keep consistency across the fleet. In this case, you're on an aircraft with 2-4-2 seating. The airline probably also has aircraft with 3-4-3 seating. Knowing that a seat is B or J tells the staff that is a middle seat.
There is a long-held belief in many cultures that the number 13 is unlucky. And many airlines have responded to this by simply missing row 13 in their seat numbering. The rows jump straight from 12 to 14. This may seem strange to make such a change in the cabin based on a superstitious belief.
