All right, I'll be fair, since in 1994 when I got this book I was obsessed with that fact, sometimes I'd go to bed thinking, "geez, it must be something so complicated" but its actually very simple, and most people just go on and on playing the game and they wont experiment.
Some walkthroughs on the net say that they can get you the full 225 points however, I happened to see one just hours ago that clearly doesn't. There are many assumptions, but after you're done (using those websites as a guide) you end up with less than 225. So they've probably just assumed those points were right or they simply lied.
Its not fair it will take you a whole game to find out its really not.
Not to degrade the walkthroughs thou, I happen to admire them a lot, they do help you get unstuck.
I accidentally found this out while replaying the game recently (a year ago perhaps). Here is the answer:
When you win the game in both the DOS and Macintosh version, if you did all the tasks right, you'll have 223/225 points. Two points are missing. When you ask Boos for the keys and he hands them to you, the game will give you [2] points. Immediately give him the keys back, HE WILL TAKE THEM BACK!... No problem, ask him for the keys again, you get [2] "extra" points... there goes the missing [2] points from the end of the game. This works in both DOS and MAC. No, this is not a glitch, just a way to test the IQ of some gamers
Now, an interesting thing to do is offer the keys to him once again [LOL]....
Anyway, you CAN do this at ANY point of the game in the DOS CD version (NOTE: in the Mac you must do it before you finish the toast or else you are TOAST!)
That means that if you have a game saved anywhere before you reach Morpheus, you CAN go back to Boos and give him the keys, he'll be delighted that you return his keys, you must perform the toast again to get the keys back thou. The two points will be added to your score.

Try it with one of your old saved games
