How to make Language Injection for custom twig tag

Hello,

In my project for templates i uses Twig engine, and for javascript purposes i create custom {% script %} tag.
Does it possible to create Javascript language injection for that tag:

template.twig:
---------------------------------------------

... some html code...

{% script %}

... javascript code here ...

{% endscript %}

---------------------------------------------

Need phpStorm to highlight javascript syntax inside the {% script %} tag.
I tried to create XML tag Injection with Value Pattern "\{% script %\}(.*)\{% endscript %\}", but it works only if the {% script %} tag placed inside some xml <tag>. In my *.twig files {% script %} tag doesn't surrounded by anything.

Is there any suggestions how to make such language injection?
