Really? I cannot reproduce that:

% kpsewhich lualatex-math.lua
/home/mpg/texmf/scripts/lualatex-math/lualatex-math.lua

Oh, well, it seems that the OP installed the new version of the file in
TEXMFHOME while the old version is in TEXMFDIST/scripts. The point is, lua files
in TEXMF_FOO/scripts have precedence over files in TEXMF_BAR/tex, regardless of
the values of FOO and BAR. So, if the old version is in TEXMFDIST/scripts, the
new one should be in TEXMFHOME/scripts in order to have precedence.

I don't think there is a universally accepted convention about that. Some
package authors place the files in scripts, some in tex, when they provide a
tds.zip archive: in this case, we don't mess with their choice. Otherwise, I'm
not sure if we have a clear policy. (Well, currently "we" means Karl since he is
the only one updating packages.)
