There appears to be a bug in the feature lookups for the upright fonts: when I ask for onum + pnum, the result is proportional lining numerals, not oldstyle ones. Just “onum” works fine (but then of course I get the default tabular figures, not the proportional ones). The italic fonts do not contain this problem. I tested with both v1.048 and the current HEAD, and both in LibreOffice and with LuaTeX; the bug appears in all cases, so the issue is really with the fonts.
