Please test code before you post. Ignoring the missing hash on your hash-bang line (#!/usr/bin/perl -w), the code if( $x =~ ($t[4]-$t[3]) > 70 * /100) { does not compile. Specfically, I get the error:
Search pattern not terminated at line 12.

As well, wrap input and output in <code> tags as well as source. This is important in this case because you are splitting on tabs, but your post does not contain tab characters. Read How do I post a question effectively?.

I am having a significant amount of difficulty understanding your spec. Assuming your first data are your input and the second are your output, the only filter I can find is that column 5 - column 4 > 217. The following code yields this result: 

#!/usr/bin/perl -w

#open (FILE,"$ARGV[0]") or die;
my @temp =<DATA>;
#close FILE;


foreach (@temp){
    my @t= split("\t",$_);

    #  $t[2],"\n";
    if( ($t[4]-$t[3]) > 217 ) {
        print "$_";
    }
}
__DATA__
aa    22    310    1    300
ab    40    200    2    228
ac    51    230    10    241
df    23    240    22    242
ef    34    370    24    282
gh    24    125    22    210
df    76    290    11    232
wq    13    170    20    180
ss    89    288    12    270

Note this is fairly messy since I tried to use your posted code. I might have written something closer to 

#!/usr/bin/perl
use strict;
use warnings;

#open (my $fh, '<', $ARGV[0]) or die "Open failed: $!";
while (<DATA>){
    my @values = split /\t/;

    if( ($values[4]-$values[3]) > 217 ) {
        print;
    }
}
