The line: 
$uniques{"$2.cfm"}++;

[download]

Increments the value stored under hash key "$2.cfm". If you haven't set it to anything, it'll end up with a value of 1 (0 + 1 = 1) :)

You then set the value of hash key "$2" to '<cust>'.

In your modified version, the line:

$uniques{"$2"}++;

[download]
Is redundant, since you're overwriting the value on the next line. I think you're looking for something like this: 
while ($_ =~ /(<cf_)(.*?)[>\s]/gi) {
  # finding custom tags
  $uniques{$2}++;
}

[download]

Then you can print out a list of how many times each custom tag is being called with something like this:

while (my ($code, $count) = each %uniques) {
  print "$code => $count\n";
}

[download]
Or, do whatever else you want with the results...
