I think you need at least read-permissions to be able to run a script
with 'sh script':
% echo 'echo hello world' > test.sh
% chmod 0 test.sh
% sh test.sh
test.sh: Can't open test.sh: Permission denied
% rm test.sh
override --------- charon/charon for test.sh? y
%
It makes sense, since sh(1) will try to open() the file for reading
the commands it contains, and having no permission to do so will stop
it from opening the file...
