There are multiple ways:
You can put "default   2" at the very top of your menu.lst which will
always select the 2nd entry (0-based) by default.
Another and maybe more modern way to do it is to add "default   saved"
at the top and then add "savedefault" below each individual entry. This
way, Grub will always select the last selected entry.
