More so than the field, the order will depend on the editors and journal in my experience.  Anecdotally, in the field I work in (Material Science&#x2F;Condensed Matter Physics) I have written and read papers in all different orders but the order seen in this paper is pretty normal to me.  You want people to get through your work (abstract, intro, results) and then the nitty gritty details come later for the people that want to use your work for something more than an interesting read.
