Maybe you guys can have a new rule that prohibits the same person from winning two builds in a row? Otherwise we may as well rename them the OCD Biomatter Charts 
On a more serious note, why not also allow highest score to be a thing? I guess that's a little more difficult to keep track of than a black and white win state, something we'd need a leaderboard to automate.
And congratulations biomatter--your discovery at the end of this run could have come at any other time, but hit right at that particularly epic moment. SO lucky... I hear biomatter was actually saved by a hostile Programmer.
About scores in general: i think Zach (from Zachtronics) is quite right with his approach: have more than one axis on which to grade(could be hard for non-puzzle) and have histograms instead of "TOP X" to see where you are in the whole. Seeing that you are "#1345" means nothing... Though currently this is not a problem but maybe for future development of automated scoreboards?
For a while I thought about changing the performance rating section of the score system (it's mostly just carried over from the 7DRL), and up until recently the plan was to do that at some point in order to take more factors into account. But now I'm starting to believe it might be good as is, because while simple, it does a pretty good job of reflecting the difficulty of a run.
Sure you can win by running for your life through the entire Complex--that's both an entirely valid win, and was designed from the start to be the "easy" road to victory. (Comparatively easy, anyway; it's not exactly easy...) But the higher your score, the more dangerous your run because you obviously encountered and overcame more obstacles, and that danger increases exponentially with your score. Not to belittle taking the stealth/speed approach, but because it allows you to circumvent some of the difficulty factors it should be somewhat less rewarding in terms of score.
Another metric I was earlier considering taking into account, one that could benefit stealth runs (in terms of score), is to include the percentage of the world that you explored in a given run, but I don't know if that's worth it. For now the value is recorded in the stats, though.
Also, as of Alpha 1b we have a new "bonus" performance component, which is used to give you points for a win, and will later on reward you for engaging in plot-related events when they become available in branches. So that could become another possible source of points for the stealth approach, akin to earning XP for roleplaying encounters in an RPG.
If you look at the 7DRL tournament results from 2012, you'll see that I'm all for recognizing alternative victories as well
. This is something that I believe will be great fun if and when we import all scoresheets into a database capable of comparing all kinds of metrics, not just score.
