Ask almost any elementary school child what number comes before twelve, and they will immediately say eleven. Ask what letter comes before K, however, and after a long pause they will start reciting the alphabet to themselves in order to figure out the answer. Letter order just isn't developed as a skill like number order. Despite the fact that you will never do math with letters, that might be a mistake. These worksheets attempt to address that issue with a wide variety of alphabetizing skills, from knowing the letters backward and forward to quickly sorting word lists.
