Perhaps premature optimization, but I'd recommend switching your tests around so that you only look for matches of numbers you care about:-

if ($data[$i] =~ m/^(?:81|82)$/ && $data[$i] eq $data[$i+1]) {

(Note the addition of anchors in the regex so you don't accidentally match a pair of, say, 181s.)

And if the number of numbers you're trying to matches is likely to grow or change often, it may be easier using a hash instead of a regex:-

my %wanted = map { $_, 1 } qw( 81 82 ); # ... for my $i (0 .. ($#data - 1)) { if (exists $wanted{$data[$i]} && $data[$i] eq $data[$i+1]) {
