Probably the ternary operator to the rescue:

sort {
    ($passes->{$a}->{'cpu'} ne '-' ? $passes->{$a}->{'cpu'} : 0)
     <=> 
    ($passes->{$b}->{'cpu'} ne '-' ? $passes->{$b}->{'cpu'} : 0)
} keys %{$passes}

UPDATE: In addition to choroba's solution you're able to assign a different value in case of '-'.
