Distinguish between AW5 and 6 in script

Question

I'm trying to create an application in Automator to automate the conversion of AW to iWork. I'm using one of Yvan's scripts to convert AW6 to iWork successfully. The only step remaining is to convert to AW6 from 5, something that shouldn't be too hard since all it has to do is open and save. However, I can't find a good way to distinguish between AW5 and 6. In his script, I believe Yvan does this here:
on AWtoAW6(leCheminOriginal_UniText) -- leCheminOriginal_UniText est Unicode text
          local leFichier, flag, nf, l, nouveauChemin
          set leFichier to leCheminOriginal_UniText as alias
          try
                    tell application "AppleWorks 6.2.9"
  activate
  open leFichier
                              set nf to name of document 1
                              if nf contains v6 then
                                        set AppleScript's text item delimiters to v6
                                        set l to text items of nf
                                        set AppleScript's text item delimiters to ""
                                        set nf to l as text
                              end if
                              if nf does not end with ".cwk" then set nf to nf & ".cwk"
                              set nouveauChemin to cheminDeStockage & nf
                              tell application "System Events"
                                        if exists (file nouveauChemin) then set name of file nouveauChemin to (text 1 thru -(2 + (length of "cwk")) of nf) & my horoDateur(modification date of file nouveauChemin) & ".cwk" (* name stamped *)
  make new file at end of folder cheminDeStockage with properties {name:nf, file creator:"BOBO", file type:fileType}
                              end tell
                              set leFichier to nouveauChemin as alias
  save document 1 in leFichier
  close document 1
                    end tell -- AppleWorks 6
          on error
                    set rapport to rapport & msg96 & nouveauChemin & return
          end try
end AWtoAW6
But I'm not sure. What I need is a script that opens, checks if it's an AW5 file, if it is opens and saves in AW6, and then proceeds to open my other script that can do the

I'm not sure what you mean. The files have to be saved as AW6 for the iWork apps to be able to open them.
Yvan has added all of his AppleWorks scripts to his Box.com account. He says the one you need is https://app.box.com/s/hqq9jwfi45nknjpf6d52
