defining sort order for mouse-buffer-menu

[mandar.mitra]

Hello,

Is there some way to customize / define the order in which buffers are
listed by mouse-buffer-menu? This is what I get when I click on
Buffers in the menu bar, or when I click control + mouse 1 in a
buffer.

I've been able to define my own sort function for use with bs-show. I
was just wondering if I can also get mouse-buffer-menu to use a user-
defined sort function.

I briefly tried msb, but wasn't able to plug in my own sort function.

Thanks for any tips,
Mandar.
