Try: awk 'BEGIN { FS=":" } { print $3 }' | sort -n -r

It works Wonders.  (Not to mention that the FS="... is a pattern in
this case and not a statement.)

The is the end of the article I intended on posting but inews has the
stupic feature that no article can have few original lines than quoted
lines.  In fact Pnews seems to have an additional feature of continual
harassment whenever you try to post an article with it.  I hate stupid
things like this.  They only provoke other stupid acts like this one
of posting more garbage to the net than before.  This is almost as
dumb as the attempt to force net.announce to be shipped to all sites
by rn refusing to work without it.  Even if net.announce is shipped
between sites (all sites) that is no guarantee that it will be read.
