I don't know if this will help, but the documention for CGI specifies a reference to an array should be passed to "head" when more than one element needs to be supplied. 
sub header_css {
    my @css_style_sheets = (
        "http://othermachine/css/standard.css",
        "http://othermachine/css/ssd.css",
    );

    my @head_links;

    foreach (@css_style_sheets) {
        push(@head_links, Link({
            -rel => 'stylesheet',
            -type => 'text/css',
            -href => $_
        }));
    }

    return \@head_links;
}
