I believe this is a function of you login shell, /usr/bin/bash.  Humor me,
try this:

exec ksh			# full path mind you
export SHELL=ksh	# ditto
echo '[[ -x $0 ]] && date' > test.sh
chmod 700 test.sh
./test.sh

If it runs via /bin/sh, it will fail to recognize the '[[' construct.
My expectation is that since SHELL is set to ksh, the shell will be run
with ksh...

truss?   New to me...........
