The META keywords tag was once of high value in the whole scheme of SEO, but since the rise of Google and the reliability of link structures META keyword tags have lost their value. It is just too easy for anyone to spam a list of tons of keywords into this tag to give it any actual merit or weight.
Most search engines ignore this tag completely for ranking a site. The only use it really has now is to actually describe what a sites theme may be about by analysis of these keywords.

This tag is pretty much worthless these days.
