I don't see any poetry here. Did you mean PLAY with numbered paragraphs? In this case, each diaglog is being treated as a paragraph for purposes of this test. Since the paragraph format for dialog is 1-3, number each speaker's dialog as in print and treat each one of these 1-3 diaglogs as a numbered paragraph.
A format is chosen according to what it IS, (numbered paragraphs), not by what it might LOOK LIKE (line-numbered text of some sort.)
Hope that helps. Let me know if it doesn't!
