He doesn't understand XSS that much, but he finds enough real issues...

I bet what happened is that he sent "<script>" to the page, and the page
generated an error because it's not a number, and that resulted in an
error message that didn't quote the resulting HTML.

Near as I can tell, PHP itself doesn't quote an error message before
returning it to the user.  If it doesn't, it should, but I don't have PHP
so I can't prove this.
