Yea, the List option is very important. Without that, each item that is within the stream will cause the script component to execute once. This will also employ the data matching method that's used within the component (longest list, shortest list, etc). When you enable the List option, all that data gets passes to the script as one big chunk, which is incredibly useful since you can deal with all of them at the same time. Also, if all the inputs are passes in as Lists, then your script will only execute once every time its recalculated.
