Use Javascript to Incrementally Add a Numer to a Selected Class
I don't think you really need to add the number to the class; the elements that you're targeting also have the .views-row class on them so you can use a bit of contextual jQuery to get the job done in a couple of lines:

$('.views-row').each(function(i,e) {
  $('.content .body', e).insertBefore($('.content .field-name-field-image-one', e));
});


I haven't tested that but I can't think of a reason why it wouldn't work.
