There is a logic for sure.The standards are renamed based on the type of assurance provided by the engagement undertaken by a member. That is, each type of engagement has a block of numbers assigned. (SAs,SREs,SAEs & SRSs).
Also there is a separate block for SQCs.
This helps in allotting numbers to new standards in a logical fashion thereby grouping relevant standards together and avoiding confusion.
