It's not possible to use ID3 tags with WAV files. It is possible to embed similar information in the WAV header but it is not widely supported and very few, if any, programs will read it.
You can add an ID3 tag to the beginning of a WAV file but then players won't recognize it as a WAV file because the first three bytes are 'ID3' and not 'WAV'.
The scripting idea described in that link is post-processing of the file; ie rip to WAV but name the file using a convention like 'Artist-Album-Track', transcode the WAV to another format that supports ID3 tags (like MP3), and then invoke yet another program via a script to take the info inferred by the file naming convention and create an ID3 tag to be prepended to the MP3 file.
