I don't think there is any connection between the order of the UEFI
boot variables and the order things are presented in grub menus.

"bios boot settings" is another thing entirely.  My "bios" only shows
one entry: "Fedora".  Even if I try to use efibootmgr to create new
entries.  Also, regarding shim.efi vs shimx64.efi (and grub.efi
grubx64.efi) - it may be the case that shim.efi is 32-bit, but still
boots a 64-bit kernel.  I don't really know.  I *assume* the *x64.efi
entries are 64-bit, and that it implies the others are 32-bit.

So, having taken a moment to look, shim.efi and shimx64.efi are
identical, and there is no grub.efi, only grubx64.efi.  So purge my
silly comments on UEFI booting in 64-bit vs 32-bit mode from your
brains.  Sorry!
