I have the same result as you have. I don't know why the order matters,
my knowledge of prepocessors is lacking.

However I recreated your document easily with:

$ dformat.awk format-test.ms | groff -ms -pe -Tps > main.ps

I did not use tbl (with the -t switch) and it worked perfectly.  You
don't need tbl for this particular document.

I noted that when producing the pdf (either with groff -Tpdf or ps2pdf),
the dotted lines appear thinner than in the postscript file.  To be
honest, I would not have noticed them if I only looked at the pdf file.
