Do you want to use this script from M-x grep? I assume "yes".
AFAICT grep.el highlights matches via a grep-mode defined as kind of a
compilation-mode. The way of highlighting is defined in
`grep-regexp-alist'. Other things are highlighted via font-lock
keywords. Of course be sure to bind grep-highlight-matches non-nil.
But in general, grep-mode should be able to highlight as you want it.
My first guess is that might be help to set grep-highlight-matches to
always -- note that this option has a :set custom specification!
If that doesn't help, please show us some code!

Michael.
