http://homepage.mac.com/jlarson7/metadata/index.html has the following script, which may be closer
==============
tell application "Aperture"
tell library 1
tell project "untitled project"
tell image version "image001"
--set value of IPTC tag "Caption/Abstract" of image version "Canon 1Ds" to "hello"
--the above won't work IF the tag doesn't already have a value because the class doesn't exist until it does. Therefore you have to make the class then set its value. See the next tell block.
end tell
tell image version "image001"
make new IPTC tag with properties {name:"Caption/Abstract", value:"hello"}
--this line will work every time even if a value for the tag exists or not.
end tell
end tell
end tell
end tell
