For example, I would like to use this theme

Most themes have support for JavaScript syntax highlighting. If it does not appear automatically, it may be because SublimeText does not recognize the file as containing JavaScript. You can force it by going to View > Syntax > JavaScript > JavaScript.

If you need to define a particular syntax, you will have to build your own syntax definition. That guide has a step-by-step process.

I would suggest copying the existing JavaScript syntax definition and refining it further, if you need to add or change a few definitions. The syntax definitions are defined by regular expressions, and held within an XML file. If your variables can be differentiated by a specific regular expression, you will be able to color-code them with a separate rule.

Sublime Text 2: diff syntax highlighting with a light background color scheme gives a succinct example of updating a theme to show different colors for new syntax.
