You can create a directory with only the scripts you want to run. Not sure if that helps.
~/.nmap (not searched on Windows)
the current directory
A scripts subdirectory is also tried in each of these.
When a directory name is given, Nmap loads every file in the directory whose name ends with .nse. All other files are ignored and directories are not searched recursively. When a filename is given, it does not have to have the .nse extension; it will be added automatically if necessary.
or looks like you can ONLY load scripts which are both in two catagories.
nmap --script "default and safe"
Loads those scripts that are in both the default and safe categories.
