SCORE is a fancy way to say ev with all parameters locked. Without SCORE, we used to say some particular game has ev of $20 if spread $160 to $10, assuming dealer is fast enough to deal 100 hands per hour. With SCORE, all parameters are locked. It has to be 100 hands per hour, bankroll $10000, player spread using one Kelly bet. So SCORE can't be 20%, must be 20, meaning the player hourly earning is $20.
Bankroll $10000 with one Kelly betting means you have to find $9.07 minimal table, but $10 minimal table is close enough.
N0 = 1000000/SCORE
For example, if SCORE is 40, then N0 must be 25000. Players want to find the game with highest SCORE (or lowest N0).
13.5% Risk OF Ruin gives optimal BR growth. Any higher RoR is costing you. Now 13.5% RoR is too high for most AP's so they opt for betting proportional to 13.5% RoR kelly optimal bets at lower bets to decrease risk. This also costs you. Playing the optimal 13.5% you should constantly be adjusting bets to your new current BR. RoR changes every time your BR changes. You adjust bets to maintain the 13.5% RoR. If you do that your are playing to almost 0 chance of busting out.

SCORE uses a standard setting for BR (10K), spread (1-10 I think), RoR (13.5%), game speed (100 rounds/hour), etc. On the other hand c-SCORE can use anything and gives you (EV/SD)^2 for whatever parameters you set. Don invented SCORE or at least popularized it as he will give credit to at least 1 predecessor with a very similar idea. Don's wish was to have SCORE refer to his concept and c-SCORE (custom SCORE) refer to anything that didn't use the standard inputs he set. Unfortunately many refused to respect Don's request and the term SCORE is often misused which causes the confusion that Don wanted to avoid.
SCORE assumes one full Kelly spread. Meaning if player is using Hi-Lo on 6D S17 shoe game, his spread will be something like this:
$40 when player advantage is 0.5%
$80 when player advantage is 1.0%
$120 when player advantage is 1.5%
$160 when player advantage is 2.0%
$200 when player advantage is 2.5%
Based on how many index plays are used, it is likely that the above conditions occurs at TC +1, +2, +3, +4 and +5.
For players using level 2 counting system, TC could be at +2, +3.5, +5, +6.6, +7 for him to bet $40, $80, $120, $160, $200. Note that level 2 TC+7 is equivalent to level 1 TC +3.5. So level 2 SCORE is higher than level 1 SCORE as his max bet out faster at the same level of risk.
