Looking at the Net::SFTP::Foreign Source, it would appear that callback is not a valid option for mput(): 

sub mput {
    ...
    my ($sftp, $local, $remotedir, %opts) = @_;
    ...
    my $ignore_links = delete $opts{ignore_links};

    my %glob_opts = (map { $_ => delete $opts{$_} }
             qw(on_error follow_links ignore_case
                        wanted no_wanted strict_leading_dot));
    ...
    my %put_opts = (map { $_ => delete $opts{$_} }
            qw(umask perm copy_perm copy_time block_size queue_size
                       overwrite conversion resume numbered late_set_p
+erm
                       atomic best_effort sparse));

    %opts and _croak_bad_options(keys %opts);
    ...

However, put() does accept callback (as well as copy_perm and copy_time): 

sub put {
    ...
    my $cb = delete $opts{callback};
    ...
    my $copy_perm = delete $opts{copy_perm};
    ...
    my $copy_time = delete $opts{copy_time};
    ...
