You should think in terms of mathematical functions not the strange (but noe familiar) imperative operations of procedural programing languages. i = i + 1 would mean 0 = 1 which is clearly a contradiction. variables do not change their value once bound in XSLT (or other functional programming languages). You should think of all the items in a for-each being executed in parallel, there is no sense in which one executed first. Just select the nodes that you want to sum with an Xpath and then apply sum() to those.
