Try: 

cmpthese (10, {
    a    => sub { a( \@foo ) },
    b    => sub { b( \@foo ) },
});

You are trying to take a reference to a sub with arguments. That doesn't work. Try Data::Dumpering the result of \&a(\@foo). It is a reference to the arrayref that a() returns... ie. perl calls the sub, then creates a ref to the result, which in turn cmpthese() can't do much with.
