It should be something like this (inside texmf-dist or wherever you
have other files, possibly in TEXMFLOCAL) plus one or two executable
files (lua/python scripts) next to other binaries like "pdflatex":

scripts/mol2chemfig/<whatever-you-want-or-need>
scripts/mol2chemfig/lua/*.lua
scripts/mol2chemfig/python/*.py

tex/latex/mol2chemfig/mol2chemfig.sty
tex/context/third/mol2chemfig/t-mol2chemfig.tex ;)

doc/latex/mol2chemfig/<whatever-you-want-or-need>
doc/latex/mol2chemfig/mol2chemfig-doc.tex !!!
doc/latex/mol2chemfig/mol2chemfig-doc.pdf
doc/latex/mol2chemfig/README
doc/latex/mol2chemfig/samples/fmn.mol
doc/latex/mol2chemfig/samples/peniciling.mol
doc/latex/mol2chemfig/samples/peniciling.tex
doc/latex/mol2chemfig/samples/plp.mol
doc/latex/mol2chemfig/samples/plp.tex
doc/latex/mol2chemfig/samples/plp2.mol
doc/latex/mol2chemfig/samples/plp2.tex

The only "tricky" part that Karl is talking about is that your
executable mol2chemfig inside binaries should be able to load all
other *.py modules inside [texmf]/scripts/mol2chemfig/python/*.py.

You asked for some examples of other programs. My TL contains the
following python scripts:
    de-macro, dviasm, ebong, texliveonfly, xasy

The "xasy" does
    import xasyMainWin
for example and the file seems to be located under
    /usr/local/texlive/2012/texmf/asymptote/GUI/xasyMainWin.py
but I'm not sure which trick exactly does the magic. And I'm not able
to run xasy either since I don't have all the required python modules
installed.

The file texmf.cnf contains
JAVAINPUTS   = .;$TEXMF/scripts/{$progname,$engine,}/java//
PERLINPUTS   = .;$TEXMF/scripts/{$progname,$engine,}/perl//
PYTHONINPUTS = .;$TEXMF/scripts/{$progname,$engine,}/python//
RUBYINPUTS   = .;$TEXMF/scripts/{$progname,$engine,}/ruby//
but I don't believe that this would work out of the box without some
wrapper script somewhere.

[Another "package" uses *a lot* of perl, ruby and lua scripts which
are located inside texmf-dist and the binaries manage to load all the
proper libraries from there using a wrapper, but people would crucify
me if I would suggest to take that package as a role model.]
