Three paras, first one is the filename you will process on, second one is how many rows will be included in each block, third one is which column you will compare on.

Here assume the column you are comparing are all integer.

Code:
$file=shift;
$rows=shift;
$col=shift;
open(FH,"<$file");
while(<FH>){
	@arr=split(" ",$_);
	$t=$arr[$col-1];
	$index= ((index $./$rows,".")==-1)?$./$rows: (int $./$rows)+1;
	if($t>=$max){
		$max[$index]=$_;
		$max=$t;
	}
	if($.%$rows==0){
		$max=0;
	}
}
close(FH);
for($i=0;$i<=$#max;$i++){
	print $max[$i];
}
