If you haven't visited Apple's AppleScript for OS X pages yet, you're missing some good stuff. For example, there's a page of toolbar scripts that can make a number of scripts accessible in the Finder.
But the real gem is the Script Menu menubar widget. As you can see in the screenshot, this menubar widget gives you system-wide access to the scripts stored in /Library/Scripts. In addition, you can easily add other scripts to the collection simply by dropping them into your user's Library/Scripts folder.
Even if you're not an AppleScript fanatic, this widget is worth a look. For example, try "Info Scripts -> Font Sampler" for a cool demo of AppleScript's power.
