I'm pretty sure "scans" is NOT an abbreviation of "scansion." "scancion" is a noun that refers to the process of scanning (verb) the verse. Will is using "scans" as a verb. In my experience, when working on Shakespearean text, people will often pick apart a line to determine whether or not it "scans" i.e whether or not it fits the meter. He's saying "that scans" as in "that piece of verse I just said scans to correctly to fit the iambic pentameter." So yes, the "scans" he uses is referring to scansion as a concept, but it's not an abbreviation. It's just a different part of speech, and a more colloquial usage.
