You can't pass a file handle to tee, it's a shell command, it doesn't understand Perl file handles.

I'd probably just print to several file handles: 

sub tee {
    my ($fhs, $strings) = @_;
    print {$_} @$strings for @$fhs;
}

open my $fh1, '>', $f1 or die "$f1: $!";
open my $fh2, '>', $f2 or die "$f2: $!";

tee([ $fh1, $fh2 ], [ 'Whatever you want to ', $print ]);
