Due to some interest shown off-list, I have made a new patch to enable
the feature to force a script to run, the patch is basically the same as
earlier but since the svn-version of nse_main has changed, so does the
nmap -p2424 target.com --script ms-sql-config --script-args force
The primary usecase people seem to have is that they e.g. do a
configuration review of a lot of ms-sql servers, say you have a list of
20 servers where the database is located on an uncomon port. They don't
want to have to do -sV --version-all just to run a script, since they
already know what's on the port.
Attached is the svn diff and the complete nse_main.lua file.

You can also do:
local force = stdnse.get_script_args(self.short_basename..".force")
This way you can select which scripts to run "script_name.force" or
force them all when "force" is specified.
But this is not a clean solution since you will specify the script name
twice. A better one would be to do it in the --script switch, perhaps
with a one char (e.g: '#', --script='ms-sql-*#' to force ms-sql* scripts)
or anything else ... (making sure to escape those chars!)
Perhaps then you will get an approval :)
I really like that idea!
I implemented it, using the @ - character. Usage :
./nmap --script @smb-brute,http-* -p80 www.google.com -d3
//This would force smb-brute, but run the http-* as normal.
./nmap --script @http-title,smb-brute -p80 www.google.com
//Forces http-title, but not smb-brute
Force does not work for categories now ("@http-*"), but I can add it on
if this suggestion gets approval. Svndiff attached.
Why wait. Here's another version, the following syntax works also:
/nmap --script @smb-* -p80 www.google.com
