That's not how resource loader works. You need to specify you want to have something loaded before you start altering it.

mw.loader.using('ext.narayam.core', function () {

  /* customization here */

});

the above will work anywhere anytime, including in Mediawiki:Common.js

Thanks Krinkle, it helped

You're welcome. I found this (small) section on the Narayam extension documentation page:

https://www.mediawiki.org/wiki/Extension:Narayam#User_level_customization

Perhaps you can improve it based on the customizations you have've created.

I tried various ways to make this work at http://sa.wikipedia.org/wiki/%E0%A4%AF%E0%A5%8B%E0%A4%9C%E0%A4%95%E0%A4%83:Siddhartha_Ghai/vector.js but couldn't get it to work. The unshift method as described at the documentation works when using the console but doesn't work as part of the userscript. Gives the error described at http://www.mediawiki.org/wiki/Extension_talk:Narayam#Formalization_of_rules

Hope a way to do this can be found soon.

I made it working and here is the code http://pastebin.com/defjdVU9 See the differences from your code.

Also updated the documentation at http://www.mediawiki.org/wiki/Extension:Narayam#User_level_customization
