How long does the average user stare at the scores on the search result page? It doesn't seem like something people would leave open. Over a short period of time, say 30 seconds, the difference in bandwidth & user experience is inconsequential between the different methods. Engineering also includes scoping resources for maximum impact, after all. Building a fancy, ultra-efficient live score system would be fun, but it's not going to be good engineering if the usage metrics don't justify it.
