In general, Referees tracking scores using the tablets and Scorekeepers working with score inputs do not need to know the score values for individual achievements, nor how they would add together. The scoring system will take all of the inputs and determine the score automatically, including any Circuit bonus, Junction Ownership, etc. that may apply.
The score inputs are meant to reflect the state of the field, though Referees must be mindful of the specific definitions and requirements needed to satisfy certain achievements as described in the Game Manual and Q&A. Once a Referee has determined that the achievement criteria has been met, they input that score into the system and it will calculate the points as appropriate.
For the point value specific questions, I encourage you to download the scoring system and input the scenarios described. For the questions that get at the requirements for something to score or how a situation should be handled, you should seek answers on the Q&A forum or Referee volunteer forum. This forum is meant for questions related to volunteering as a Scorekeeper or providing technical support and guidance on how to use the scoring software and cannot give answers related to gameplay, rulings, etc. as mentioned in the original question.
