Change installed AppleScript version Is there any way to change the installed version of AppleScript?

After mistakenly identifying my version of AppleScript as 1.0 by using a 15 year old script (turns out that just checks the version of the script you are currently running, which is implicitly 1.0) and trying to figure out how to upgrade, I was wondering how/if it's possible to change the installed version of AppleScript?
You can not change the version of AppleScript installed with OS X. AppleScript is a core part of the operating system.

If you are running the latest version of OS X, then you have the latest AppleScript.
