Creating a list of actions that will earn the player points, and using this both to change the score and to give FULL SCORE reports.

We could, if we wanted, make a table of stored actions all of which represent things that will earn points for the player. For instance:

"Bosch"
Use scoring.
The Garden of Excess is a room. The gilded lily is an edible thing in the Garden of Excess.
The Pathway to Desire is west of the Garden of Excess. The emerald leaf is in the Pathway.
Table of Valuable Actions
relevant actionpoint valueturn stamp
taking the emerald leaf15-1
eating the gilded lily5-1

(And our list would presumably continue from there, in the full game.)

The maximum score is 25.
After doing something:
   repeat through Table of Valuable Actions:
      if the current action is the relevant action entry and turn stamp entry is less than 0:
         now the turn stamp entry is the turn count;
         increase the score by the point value entry;
   continue the action.
Understand "full score" or "full" as requesting the complete score. Requesting the complete score is an action out of world.
Check requesting the complete score:
   if the score is 0, say "You have not yet achieved anything of note." instead.
Carry out requesting the complete score:
   say "So far you have received points for the following: [line break]";
   sort the Table of Valuable Actions in turn stamp order;
   repeat through the Table of Valuable Actions:
      if the turn stamp entry is greater than 0:
         say "[line break] [relevant action entry]: [point value entry] points";
   say line break.
Test me with "eat lily / w / full score / get leaf / full".
Test me with "eat lily / w / full score / get leaf / full".
Garden of Excess
You can see a gilded lily here.

>(Testing.)

>[1] eat lily
(first taking the gilded lily)
You eat the gilded lily. Not bad.

[Your score has just gone up by five points.]

>[2] w

Pathway to Desire
You can see an emerald leaf here.

>[3] full score
So far you have received points for the following:

eating the gilded lily: 5 points

>[4] get leaf
Taken.

[Your score has just gone up by fifteen points.]

>[5] full
So far you have received points for the following:

eating the gilded lily: 5 points
taking the emerald leaf: 15 points

This system is tidy, but limited: we cannot give actions interesting names in the score list, like "seducing the pirate's daughter" or "collecting a valuable artifact". So it will not be ideal in all situations, but it has the virtue of being easy to extend, and of listing all of the player's successes in the order in which they occurred in his play-through.
