Any solution is going to be expensive.
  1. Don't eat memory: 
    my $ignore = '(^The )|(^A )';
...
@sorted = sort { 
    $a =~ s/$ignore//;
    $b =~ s/$ignore//;
    lc( $a ) cmp lc( $b );
  } @indata;

  2. Or store better keys first: 
    %data = map { my $data = $_; s/$ignore//; ($_, $data } @indata;

@sorted = @data{ sort{ lc( $a) cmp lc( $b)} keys %data };

Hope this helps,
