Here is one method: 

my %bits;
my @fields= qw( organization report poise hair swimsuit
    question bribe connections );
@bits{@fields}= map { 1<<$_ } 0..7;
sub mask {
    my $mask= 0;
    $mask |= $bits{$_}  for @_;
    return $mask;
}
my $byte= 0;
foreach my $field (  keys %bits  ) {
    $byte |=  $bits{$field}   if  $obj->{$field} =~ /\S/;
}
# ...
if(  $byte & mask(qw( organization swimsuit question bribe ))
       == mask("organization")  ) {
# ...
} elsif(  $byte & ~mask("question")
            == mask("swimsuit")  ) {
# ...
} else {
    die "Contestant cheated!\n";
}
