While you're probably correct about it being understandable when read aloud, I could not make heads nor tails of that passage until I read your translation. In some cases the words had no meaning (e.g. "shoures soote"). In other cases it is decipherable only if the rest of the passage is understood (e.g. figuring out that "flour" means "flower" from the context). In yet others, the archaic spelling distracts from the meaning (e.g. "veyne in swich licour").
