Bibtopic, and sorting

Hey,
I'm following-up after an exchange on fr.comp.text.tex.

1- On bibtopic and jurabib : for the sorting to be correct, you need to 
cite in your .tex file all the references contained in the .bib file. 
(This apparently because of a \citation{*} put in the .aux file.)

2- To correctly sort archival references, you may add this to 
jurabib.bst  :

FUNCTION{is.a.number}
{
   #1 swap$
   {duplicate$ #1 #1 substring$ duplicate$ "" = not}
     {chr.to.int$ duplicate$ #47 > swap$ #58 < and
       {#2 global.max$ substring$}
       {pop$ pop$ #0 ""}
     if$}
   while$
   pop$ pop$
}
FUNCTION{add.zeros}
{
   duplicate$ is.a.number
     {"000000000000000000" swap$ *
      #-1 #20 substring$}
     'skip$
   if$
}

And in the "presort" function, replace
      sig1 field.or.null sortify
with
      sig1 field.or.null add.zeros sortify
(and so on with sig2, sig3 and sig4).

Huge thanks to Nicolas Markey (hurrah!)
