The explanation above deals with your question; now, an unsolicited comment; not because it's better, but because it's a useful alternative in some cases: 
#!/usr/bin/perl
use Modern::Perl;
# 945665

my $count=0;
my $num;

my @arr = <DATA>;
for (@arr) {
    $num=0;                  # nul $num to avoid probs from persistenc
+e in $1
    if ($_  =~ /(\d+)/ ) {   # as an alt to splitting on the tab
        $num = $1;
    }
    if ($num > 600) {
       say "$num > 600ms";   # OP didn't ask for this, but /me 
                             # likes visual confirmation in the output
       $count++;
    } else {
        next;
    }
}
say "\t count: $count;"
