That behavior also requires GRUB_SAVEDEFAULT='true'. By itself,
GRUB_DEFAULT=saved merely causes grubenv to be consulted for what to
boot rather than it being statically defined in the grub.cfg.

Look at the grub.cfg and find the menuentry you want:
menuentry 'Fedora, with Linux 3.17.4-301.fc21.x86_64' --class fedora
--class gnu-linux --class gnu --class os --unrestricted
$menuentry_id_option
'gnulinux-3.17.4-301.fc21.x86_64-advanced-f3332d09-65f9-48c5-8539-c2b9ec8c75b4'
{
And copy-paste the last section, using it in this command:
grub2-set-default
'gnulinux-3.17.4-301.fc21.x86_64-advanced-f3332d09-65f9-48c5-8539-c2b9ec8c75b4'
Or set it as GRUB_DEFAULT= in /etc/default/grub and the make a new
grub.cfg with grub2-mkconfig -o /boot/grub2/grub.cfg

It might be helpful but I see it mainly targeted at developers who are
boot and OS install oriented. It's not really an end user manual, and
grub isn't really meant for interaction by users.
