All executable files in this directory are processed in shell expansion order.
00_*: Reserved for 00_header.
10_*: Native boot entries.
20_*: Third party apps (e.g. memtest86+).
The number namespace in-between is configurable by system installer and/or
administrator. For example, you can add an entry to boot another OS as
01_otheros, 11_otheros, etc, depending on the position you want it to occupy in
the menu; and then adjust the default setting via / etc/default/grub.

grub2 is so hard on me to try and play with. As well as the etc forum bug for this post. A lot of debugging went into making this post stick. On a 9 inch screen.
Sigh. Maybe you can compare text files I posted with yours.
