We are comparing fixed length strings of digits. The result is the same whether we compare them lexically or numerically. I chose the lexical sort because the strings do not seem to have any numerical significance.

Thanks for supplying the link to the module documentation.

UPDATE: Oops! My comment about no numerical significance is wrong. My comment on the subject in level 6 below applies here as well (as long as all fields are of fixed length). I still prefer the lexical sort, but it is harder to justify.
