Accumulate lines until you reach a BS line, then output what you have accumulated. 
while (<$fh>) {
   if (my @queue = /(\w+) \((\d+)% \/ (\d+) of \d+ \| event (\d+)% \/ 
+(\d+) of \d+\)/) {
      push @queues, \@queue;
   }

   elsif (my ($group) = /^BS: (\w+)/) {
      while (@queues) {
          my $queue = shift(@queues);
          print(join("\t", $group, @queue), "\n");
      }
   }
}
