Maybe a limitation of legacy_kernel.
Normally to use labels in grub2 the 'search' command is used without any 
reference to the device assignment.
Like:-

menuentry 'Mageia-2 multiboot' {
search --no-floppy --label --set=root mageia-2
multiboot /boot/grub2/i386-pc/core.img
}

That syntax is apparently correct, as legacy_kernel needs to know what 
the original legacy command was.
I have tested here in a clean mga3 installation and it works for me.

Please re-test and if it fails again please attach the original menu.lst 
and the resulting grub.cfg along with any error messages.
