Thank you for confirming that.

We can't simply use fc-match (i.e. FcFontMatch ()) because
it returns a font that doesn't match with :lang=ml if
there's no such font.  Perhaps we can use FcFontSetSort()
function on the result of FcFontList().

I found that this is because qsort doesn't preserve the
original order if scores of two elements are equal.

Please wait again for a while.  I'm now working on it.
