Line 15:
# Order matters; Do you mean 1 + 5 is not the same as 5 + 1? Or do you mean that each coin of the same denomination should be treated separately? (''This'' 1 unit coin is different from ''that'' 1 unit coin.) If that is the case there needs to be something that makes them unique.
# 'Count the coins' is a poor name for the task anyway, especially if you are going to have a restriction that order matters. By definition order doesn't matter when making change. It isn't counting coins, it's counting sums.
Stated another way; say, for instance, you were assembling power packs from different canisters of highly reactive fuel. Once you opened a canister, you must use all of it and the power pack has a tightly defined capacity requirement. Your power pack needs to have a capacity of 6 power units and you have fuel canisters with [1, 2, 3, 4, 5] units of fuel. How many ways can you resupply the power pack? Now. How is ''that'' problem substantially different the the one ''you'' stated? And what does it have to do with counting coins? See why 'counting coins' is a bad name?
