Using \tibfont like this, with \tibfont declared as a \font, means that 
you're overriding whatever fontspec had set up earlier. This was a raw 
XeTeX way of accessing the font, as I wasn't sure how to do it via 
fontspec. If you use fontspec instead, you'll get a \tib command that 
matches the current font size, rather than using one fixed style.

So you probably want something more like:

     \newcommand{\tib}[1]{{\fontspec[AssortedTibetanFeatures]{Tibetan 
Machine Uni}%
         \lineskiplimit=-100pt \baselineskip=16pt #1}}

or better still, make the \baselineskip value depend on the current 
font size. I'm sure some of the LaTeX experts around can tell how to do 
that. I just picked an arbitrary value that seemed to look OK to me for 
the sample, but it's not flexible/robust to do it that way.
