How do I get the Photoshop layer tags in JavaScript?

I asked this question at graphic design stack exchange but they pointed me here:

I want to do actions based on the tagged layer color (these thing 1) in Photoshop. I can't find a property inside the JavaScript documentation or the ExtendScript Toolkit that might contain the value.

I'd prefer not to abuse the name for that, the layer tags look like a very clean solution to my problem. If only I could fetch them.

Any Ideas?

Kind Regards,
