The rule was introduced in 2.20, so it has been around for a while. You're quite right that you can run HTTP on ports other than port 80, but it's not particularly common. The S/O ratio for this rule in 2.55 (in STATISTICS.txt) is 0.843, so it's not a particularly wonderful rule and explains why it has a maximum score of around 0.6. So the answer is that the presence of a URL in a mail using a non-standard port for HTTP is at least suggestive that the mail may be spam, since it's much more likely to be seen in spam than non-spam. But it's by no means conclusive which is why it has a low score. The question is somewhat analogous to asking, "Why does a message in HTML with odd fonts and lots of colours get a high score? Surely people are free to send HTML mails with odd fonts and lots of colours?" - the answer is the same: such mails are statistically more likely to be spam.
