Organization of Information question??

I have to write an argumentative essay for American Literature, and one of the questions on my planning sheet says this:

"Which pattern of organization will you use to present your details, and why? State specific details that make this pattern appropriate. Common patterns of organization are order of importance, logical order, chronological order, and spatial order."

I just want to list my arguments in order of which I think will support my claim the most. Is that in order of importance, or something else?
