You could use the perl library /usr/ports/audio/p5-MP3-Info. The following
snippet shows how I did it:

        # Now remove ID3v{1,2} tags
        my $tag =3D get_mp3tag($filename);
        if (defined($tag)) {
                # make a backup
                my $backupname =3D $filename . ".BAK";
                system("cp", $filename, $backupname);
                my $bytes =3D remove_mp3tag($filename, "ALL");
                if (!defined($bytes)) {
                        # restore backup
                        system("mv", "-f", $backupname, $filename);
                        dowarn("could not remove ID3 tag from $path");
                } elsif ($bytes =3D=3D -1) {
                        # restore backup
                        system("mv", "-f", $backupname, $filename);
                        dowarn("no ID3 tag found in $path, should not happe=
n");
                } else {
                        system("rm", $backupname);
                        dowarn("mp3 changed ($path): tag of $bytes bytes " .
                                "removed");
                }
        }
