He didn't allow for spaces between the two equals signs. Try this version: 
my $re =  qr[<!--QBlastInfoBegin \s+
  RID \s* = \s* ([\d-]+) \s+
  RTOE \s* = \s* (\d+) \s+
QBlastInfoEnd  \s+
-->]x;

As for the pluses, they are quantifiers and make the expression match one or more spaces (in this case). See perldoc perlre for more info.
