I'm not familiar with marcedit.pl. I'd use MARC::Batch and its related modules,
similar to the mock-up listed below (which assumes the 008 to be present to
insert the new field(s) in the proper order; I've thrown the code together
haphazardly, so it may contain errors). Of course with 006 and 007, you also
run into length issues--006 is always 18 bytes; 007's length depends on the
category of material. If the fields don't have the correct length, some systems
may reject the records.

use MARC::Batch;
#$inputfile = "path_to_your_file_however_you_get_it";
my $batch = MARC::Batch->new('USMARC', "$inputfile");
#$exportfile = "path_to_your_file_however_you_get_it";
open(OUT, ">$exportfile") or die "Can not open $exportfile, $!";
RECORD: while (my $record = $batch->next()) {
# $field006 = ''; #string of valid 006 characters (change 006 to 007 for
007)
my $new006 = MARC::Field->new( '006', $field006);
$record->insert_fields_before($record->field('008'), ($new006));
print OUT $record->as_usmarc();
}# while records
