Your "best bet" may be 443/tcp, since many networks may just allow this encrypted, binary, traffic.

OpenVPN by default uses UDP port 1194, so it is common for firewalls to monitor port 1194 (and other commonly used ports), rejecting encrypted traffic that tries to use it (or them). TCP port 443 is the default port used by HTTPS (Hypertext Transfer Protocol Secure), the protocol used to secure https:// websites, and used throughout the OpenVPN for Android.
