[luatex] luaotfload: Random font changes with mode=base

If I compile this document more than once (I think I have now
compiled it and similar documents around 200 times ;-))

\font\sup={name:Linux Libertine O:+onum;+sups;mode=base}

then in around 50% of the pdf the numbers are (as wanted)
superscripts, and in the other pdf the numbers are normal old style

I can accept that you can't combine onum + sups, but why is the
result so random? (with mode=node +sups wins always).

(Btw: The starting point was a real document which used oldstyle
numbers together with the realscript package.)
