The charset element suggests that fontconfig thinks the font covers ASCII
digits (those are one bit per char).  So the problem is not with your code.

Well, checking the font in fontforge, it does have glyphs for ASCII digits. 
Something's wrong with the cmap.  Normally you don't see them mapped, but
select "Compact" encoding in fontforge and you see that glyphs ids 125 on are
the digits.
