I prefer avoiding map in a void context, and would go for:

$total += $_ for @numbers;

Before 5.8.1, there was more point to this distinction: map built a
list that you were just discarding. Now the compiler is smart enough
that map in a void context doesn't build the list, so there's no
efficiency issue. I still find the for version more readable.

I probably wouldn't use List::Util just for this, but if I were
already using it for, say, max or min, then I'd use sum.
