Sorry to hear that, but you still stand a chance as you are on the reserve list.
Regarding the score, I believe it is like this:
Excellence: x/5
Impact: y/5
Implementation: z/5
Score = (x*0.5+y*0.3+z*0.2)*20
Now what if anything is the objective difference between, e.g., 4.5 and 4.6 on, for instance, excellence, is of course debatable.
