script objects

Why am I getting an error whenever I try to compile a script that has a script object with a variable name for the object. For instance, this code won’t compile:
script point property x: 0 property y: 0 end script
But, if I take out the word point from the script line it compiles.
script property x: 0 property y: 0 end script
This is almost an exact example from the AppleScript Language Reference, but I do get the same behavior with the exact examples. I’m using Mac OS X 10.1.3 with Script Editor 1.7, but I get the exact same behavior when I use Mac OS 9.2.2 with Script Editor 1.6 for that OS.
The error received says “Expected end of line, etc, but found “script”.” and it highlights the word script in the end script statement.
Thanks, Chuck
