[AS] How can I find files created in CS2?

Question

My company has 2000+ documents in a sytem that have been created using both InDn CS2 and CS3.
I need to be able to list all of the files that have not been updated to CS3. I've tried querying a known CS2 file using applescript and the FInder but the result only gives me InDn with no version.
I've asked for: file name, creator type and product version when querying the file, but product version doesn't give any result.
Result is (*Vue.indd, InDn, *)
Can this be done from the finder or do I have to script InDesign to query the documents? Obviously using InDesign will increase the query time.
Thanks for taking the time to read this.

If you need to figure out version of both Window and Mac files from a Mac, this is how I do it:
--Parse file type for version
on parseFileType(myFile)
     set fileVersion to ""
     tell application "Finder"
          set thisFileType to file type of myFile
     end tell
     if thisFileType ≠ "" then
          if thisFileType = "IDd3" then
               set fileVersion to "3"
          else if thisFileType = "IDd4" then
               set fileVersion to "4"
          else if thisFileType = "IDd5" then
               set fileVersion to "5"
          else if thisFileType = "IDd6" then
               set fileVersion to "6"
          else
               log "Getting version by hand..."
               --Adobe InDesign 3.0
               --Applescript sucks at parsing large files, use grep instead
               set grepString to "Adobe InDesign [0-9]"
               set theCmd to "grep -rao \"" & grepString & "\" \"" & POSIX path of myFile & "\""
               log theCmd
               set grepResult to ""
               set grepResult to do shell script theCmd
               if length of grepResult > 1 then
                    set fileVersion to (characters -1 thru -1 of grepResult) as string
               end if
          end if
     end if
     return fileVersion
end parseFileType
