Okay, first of all, but I guess you know, you can't copy code directly from another game because that game will use different flags, variables, object names, views, pictures etc... You can have a look at how it does things and try to do the same things so it fits into your game, but don't just copy them.
Secondly, there are many aspects about objects, and we can't know what you did wrong without seeing the source, we can only guess. I would guess that either animate.obj(); is not before the other object commands, that the object is not drawn, that you missed out an important command for objects or that you gave it a wrong view/loop/cell number, but that would give an error message.
There is no game that tells you everything, but there are lots of good tutorials out there about individual things. There is a series of three tutorials only on backgrounds, priorities and control lines which is very easy to follow. Read as many tutorials as possible. Also work through the tutorials at
http://members.ozemail.com.au/~ptrkelly/agi/docs/index.html using the tutorial game. If you work through the tutorials, you will know all the basics about doors, items, priorities, control lines. Really work through those!
About score, there are two variables that control the scores, you can set them to the values you like. You find their numbers in the help file in the variables section. Just set the value of the maximum points variable just before the intro, and increase the other variable whenever you want the player to get points.
