Well, maybe. The <noscript> content might itself be a suitable alternative, rather than a link to an alternative or some explanation/apology regarding the absence of the scripted feature. It all depends on what you were trying to achieve with the script.

Still, you are absolutely correct regarding the use of a DDR as a first line of defence. Use the DDR to avoid sending things to the client that won't work or could even be harmful. After that, use it to select what is best for the device from whatever options are available to you. Of course, the BPs should also give you pointers as to how to proceed when you are unfortunate enough to be without a good DDR. Proceed with caution, is perhaps the best advice.

Now I understand, the DDR should be the first line of defence. If you 
know that device doesn't support script then don't even bother with 
script or noscript.

If you are unsure, and use the noscript element, I would add that it 
should contain a minimal explanation and a link to an alternative, to 
avoid unnecessarily sending people alternative content they may not need 
or ever read.
