Instead of turning off the warning, you could sort your data using the Schwartzian Transform. 

my @new = map { $_->[0] }
          sort { $b->[1] <=> $a->[1] }
          map { [ $_, (split( /\s+/, $_, 2 ))[0] ] }
          @old;

The example assumes all of your data is in the same format as it is given in your post (a number separated from the rest of the string by whitespace).
