Wrong partition ID for known good grub2 boot

This is what I get :
" Boot Info Script 0.61 [1 April 2012]
============================= Boot Info Summary: ===============================
=> Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of
the same hard drive for core.img. core.img is at this location and looks
in partition 94 for ."
When I know its booting off of hd0,msdos7
I've seen this strange large number appear in previous RESULTS.txt files.
grub is installed on hd0,msdos7
I don't what or how it determined partition 94, was the boot partition.
I have seen this before with similar numbers.
I think I found the issue. Creating mbr boot from Ubuntu Saucy 13.10, causes the odd partition#'s. Creating mbr boot from Ubuntu Precise 12.04, everything is normal.
either a change in grub or how the mbr gets written.
So what's the solution? Install 12.04 in an old partition and purge and reinstall grub-2 from there? Or do the same from 14.04? And what's the "." mean? Some variable that didn't get set? I'm on a system with 2 Ubuntu 13.10 installations and 1 14.04 and I have this exact same behaviour. I'm trying to automate detecting where grub stage 2 files are for a bash script of my own and if I can make this work properly, I'll try to grep the result out of the results file. Thanks if you can help.

Ubuntu 14.02 uses grub 2.02
It seems the offsets in the image file has changed.
Any chance on getting an updated script?
