It's vital that CSS is above JS in the <head>, but if you're really going for it, more control is needed: https://speakerdeck.com/csswizardry/get-your-head-straight?slide=39. But as a start, getCssJsHtml() could accept an argument to either ouput CSS or JS, or new methods could be added that do the same thing (getJsHtml(), getCssHtml()). That way, the designer can put custom code between CSS and JS in head.phtml.
