You'd need single quotes instead of double there.  (And == is illegal in
Bourne/POSIX shell test commands; only bash tolerates it.)  You could
also use a function instead:

check() { test $? = 0; }
my_task; check || exit 1

Or, you could avoid the extra definition and simply check directly:

my_task || exit 1

my_task || { echo "error occurred" 1>&2; exit 1; }
