I was hoping someone on here could tell me what formula the writer(s) used to generate the ability scores of the pregenerated characters that are printed in the module. Any help would be appreciated. Thanks...

I'm not sure, but I think it was Arbitrary or DM Fiat... I was involved in the process a bit, but it was far more important to develop well rounded, balanced and interesting characters than stick to any existing guideline for stat assignment. When tweaking to get things to "feel right" we'd often just suggest bumping an attribute up or down a peg rather than "re roll" an entire attribute array.
