It looks like «string-collate-lessp», when used with the POSIX locale,
is equivalent to «string<». The examples I tried out all came up the
same, and [1] (headline «LC_COLLATE Category in the POSIX Locale») says
the POSIX collation ordering is the same as the ASCII codeset. glibc
adheres to this too (cf. /usr/share/i18n/locales/POSIX).

[1] 
<http://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap07.html#tag_07_03>

In that case the extension to the test case might be better left out.

When I was looking into this yesterday I noticed that glibc ships a
locale definition file that specifies collation according to ISO 14651
(which most language locales derive from), but unfortunately the POSIX
locale doesn’t use that.

Kind regards,
