of course it does. you can see from yourself in the mod_perl test suite:
t/response/TestAPI/err_headers_out.pm [21]:
$r->err_headers_out->add('X-err_headers_out' => "err_headers_out");
using the set() or add() interface is the preferred method, over the tied
interface shown below.

this documentation is for the compat layer. I can't recall offhand whether
this syntax works without Apache2::compat or not.
but regardless, so you know, the first example adds to any existing
Set-Cookie outgoing headers, and only in the headers_out table, which will
not persist across REDIRECT responses (use err_headers_out for that). the
second example overwrites any existing Pragma headers in headers_out table.
