Thanks! I have committed the scripts in r16647. This is the output I get
from a fresh MacPorts installation of MongoDB:

Here's an idea for both of the scripts: When you get a response, you can
set the service version with the set_port_version function.
        http://nmap.org/nsedoc/lib/nmap.html#set_port_version
Then the port name won't be "unknown" in the output. Additionally, with
monogdb-info, you can set the version number. See
        http://nmap.org/book/nse-api.html#scripting-tbl-port-version-values
for the full list of things that can be set.
