I don't think "DOM script execution context" is such a general term and
it's not clear what the difference between "script execution context"
and "DOM script execution context" is.

Since the meaning of well-understood terms like "user agent" is
established in the document, the Working Group seems to disagree
with you.

In case of ECMA-262 this seems incorrect, e.g. for

  <script>...</script>
  ...
  <p onclick="...">...

control would enter at least two different execution contexts. I am
also not sure what the "global object" would be in, say, PerlScript.

I'm just asking for the term beeing well-defined, just like the document
defines terms like "root document", "child document", "user agent", and
so on.
