The connection between Moodle Benchmark and scalability? True, it does not give you a figure of scalability but brilliantly simple in finding certain (common) bottlenecks. Anyway, your set up passes all the tests well. (The absolute numbers don't say anything, you have to compare them with the two limits the benchmark proposes. See the columns Accpt. limit and Crit. limit in http://www.syndrega.ch/blog/#benchmarking-moodlebox-on-different-raspberry-pi-models.)
But your score is not brilliant, I expected your server to touch 50.
What I don't understand is, why you utilize this quiz delay plug-in, when your server should be capable of carrying the load without. The plug-in is one more parameter in the search - a less-known one. I would test without. And instead of real loads, I would use JMeter for reproducible loads. On the monitoring side, I would dig further in to iowaits.
