One problem complicating that scenario is that many advanced Versions of technologies cost exactly the same as the simpler ones, sometimes they cost less. For example, angine III costs less than engine I, shouldn't it give you a higher score representing your higher tech ship? Same with the guns, a wavemotion III costs the same as wavemotion I, shouldn't you get a higher score for the more advanced gun? If you go by the resource cost (and I assume that you were only using minerals as an example, not claiming that only minerals should be counted) then the advanced ships will often cost the same as a basic ship.
