Alphanumerical + -ly (the adverb suffix). This creates the adverbial form needed when describing how something is done using alphanumeric systems.
Programming languages often need to sort data 'alphanumerically'—placing both text and numbers in a sensible order—and different languages handle this differently, which is why a list might sort as '1, 2, 10, 20' (numerically) versus '1, 10, 2, 20' (treating digits as text).
