The general approach seems perfectly reasonable to me. However I think you have a problem with the implementation: the methods you are injecting will be closures over the current $self, so it won't work if you have more than one object in the class.

I also think the code would be easier to read (and therefore maintain) if you create the method then goto it, rather than duplicating the functionality, something like (untested):

  die "No such method $AUTOLOAD. Barfing\n"
      unless exists $self->{$field};
  if ($self->{$field}{editable}) {
    *$AUTOLOAD = sub {
      my $self = shift;
      $self->{$field}{value} = shift if @_;
      $self->{$field}{value};
    };
  } else {
    *$AUTOLOAD = sub {
      my $self = shift;
      die "Can't modify readonly field '$field'" if @_;
      $self->{$field}{value};
    };
  }
  goto &$AUTOLOAD;
