No, they aren't! Try this:
[EMAIL PROTECTED]:24:44] >> ~/test
--> dd if=/dev/zero of=test.sh count=1
1+0 records in
1+0 records out
512 bytes (512 B) copied, 6.5e-05 seconds, 7.9 MB/s
[EMAIL PROTECTED]:24:46] >> ~/test
--> chmod a+x test.sh
[EMAIL PROTECTED]:24:55] >> ~/test
--> ./test.sh
bash: ./test.sh: cannot execute binary file
