We've already had some discussions about this - here's one from September: [webmasterworld.com...]

There's not a lot of solid information from Google about the exact "how". My assumption is that it works something like the widely used Flesch-Kincaid reading ease assessments (used in MS Word). That would mean important factors are average number of words per sentence, and average number of syllables per word.
