Answer 1

In doc you can find next lines

Note: that a named property will match properties on the same level only , while the special $ property will match properties on the same level or deeper. Eg an array item like {name: {first: 'John', last: 'Doe'}} will not be matched by {name: 'John'} , but will be matched by {$: 'John'} .

So, i your case you can't use it as you wish.
But, you can use

function(value, index, array): A predicate function can be used to write arbitrary filters. The function is called for each element of the array, with the element, its index, and the entire array itself as arguments.

Like this

$scope.comparer = function(o) {
  if (!$scope.pfFilter) return o;
  return o.PackagesViewModel.filter(function(el) {
    return el.PlatformId == $scope.pfFilter.PlatformId
  }).length;
}
