Try backticks `...` instead of $(...)
Code:
ret =`echo Q | timeout 5 openssl s_client connect "${1`hostname`}:${2-443}" -ssl3 2> /dev/null`

Maybe?

Code:
ret=$(echo Q | timeout 5 openssl s_client connect "${1-`hostname`}:${2-443}" -ssl3 2> /dev/null)

you invoke bash but the error says sh.

did you replace bash with sh?

if you have access to the webserver from your local box you can just run poodle checker using the other machine as the argument:

Code:
./poodleCheck a2.blahblah.com

But Aia's solution is correct. You are missing a - after 1
