You're making a common bash programming mistake, explained here:

(grub-script is modeled off of bash syntax).

To achieve that in grub-script you could use the following:

if keystatus --ctrl; then
  if [ -f ${prefix}/greffons/menuentry.cfg" ]; then
    source "${prefix}/greffons/menuentry.cfg"
  fi
fi
