No, that's not correct. Files are created using the permission
bits used in the applications call to creat(2) or open(2), just
modified by the current umask. It's not the responsibility of
Cygwin to change modes and it will not do it. That has nothing to
do with ntsec and as long as ntsec is switched on, the permissions
are only generated as it's usual on POSIX systems. There's no
code which checks for the content in any way to change the
permissions on create time.

Did you look into libtool if the script is actually created using
x-bits or if a chmod is called on the file which perhaps fails?
