I want to acheive similar output but from array.

Why?

I want to use the IP address multiple time for various purpose in my script so I am pushing them in an array.

The question was why do you want an array?

Tried this, following an example but output is not as I want it. Output is not sorted and where do I specify that I only want top n unique values.

But why did you try that?

Why should that code produce something sorted?

What series of steps does the code perform to produce a sorted array of IPs and hits?

Also, what do you mean where?

Please think about it, and try to answer these questions out loud ; speak the answer to your monitor or an object on your desk.

What I would do is redirect the output of the first program to a file, then execute head --lines=N file to get the top N results

This is one approach, but I doubt its easier to understand than using "head --lines=N file" 
my %Uniq;
while( my $Ip = NextIp() ){
   $Uniq{$Ip}++
}

my @TopDown = sort { $Fun{$b} <=> $Fun{$a} } keys %Uniq;
my @TopTen = @TopDown[0..9];

# @TopTen =  ( sort { $Fun{$b} <=> $Fun{$a} } keys %Uniq )[ 0 .. 9];

or 
my @Top = sort { $b->[1] <=> $a->[1] } map { [ $_, $Uniq{$_} ] } keys 
+%Uniq;
undef %Uniq;
@Top = @Top[0..9];
