Applescript para importar correo con archivos adjuntos en un enlace de pensamiento que expandiría los archivos archivados

Mi flujo de trabajo es etiquetar y poner todos los documentos entrantes de Mail.app en Devonthink. Hago esto con Applescript. El script está funcionando bien para mí con una excepción: no sé cómo hacerlo para expandir los archivos .zip y .rar en los archivos adjuntos antes de moverlos a Devonthink. Probablemente requeriría Unarchiver o alguna otra utilidad de archivo de secuencias de comandos. Agradecería sus sugerencias. Mi script está debajo.

        set theFolder to (POSIX path of (path to temporary items))
        if the length of theSelection is less than 1 then error "One or more messages must be selected."
        repeat with theMessage in theSelection
