Yes, you are right: LC_NUMERIC is enough.
The whole locale stuff is only needed because inkscape wants "," as 
decimal "points" in german locale (which is a bug in inkscape IMHO)

So just do a (from osm2tiles.pl)

my $old_locale = setlocale(LC_NUMERIC);
setlocale(LC_NUMERIC, "");
my $export_area= sprintf("%f:%f:%f:%f", $sx1, $sy1, $sx2, $sy2);
setlocale(LC_NUMERIC, $old_locale);

around the line where the "export area" for inkscape is generated and 
everything should go well!
