The old convention was that it went in the exec/ directory, but as you

http://cran.at.r-project.org/doc/manuals/r-devel/R-exts.html#Non_002dR-scripts-in-packages
it can be in inst/anyName/. A minor convenience of exec/ is that the
directory has the same name in source and when installed, whereas
inst/anyName gets moved to anyName/, so debugging can be a tiny bit
easier with exec/.
Having just put a package (TSjson) on CRAN with a python script, here
are a few other pointers for getting it on CRAN:
-SystemRequirements: should indicate if a particular version of python
is needed, and any non-default modules that are needed. (My package does
not work with Python 3 because some modules are not available.) Some of
the libraries have changed, so it could be a bit tricky to make
something work easily with both 2 and 3.
-You need a README to explain how to install Python. (If you look at or
use mine, please let me know if you find problems.)
Better to describe exactly what you need: installation instructions go
stale very easily.
-The Linux and Sun CRAN test machines have Python 2 whereas winbuilder
has Python 3. Be prepared to explain that the package will not work on
one or the other.
Not true. Linux and Solaris (sic) have both: the Solaris machines have
2.6 and 3.3.
For an R package how does one go about specifying which should be used?
Please do not spread misinformation about machines you do
not have any access to.
Another option to system() is pipe()

Up to you as you control the path. As "Writing R Extensions" explains,
everything below the (source) directory inst/ will get installed. I
like
inst/extScripts/ (or similar) as it denotes that it is an external
script.
As an example, the gdata package has Perl code for xls reading/writing
below a
directory inst/perl/ -- and I think there are more packages doing this.
