Just add it as <script src="whatever/map.js"></script>
If they don't have javascript enabled, they won't load it.
You can load the secondary ones from map.js by using importScriptURI()
or simply add more <script src="">, as the cost is negligible, just one
line.
I wasn't 100% sure, but know that the amount of JS being loaded needs to be minimized and optimized -- even for users that do have JavaScript. Linking to external JS files is the best way to go, with minimal amounts of JS placed inline by the parser.
