在CakePHP表单/模型上的自定义验证中使用核心验证?

Using CakePHP 1.3

I understand the example at http://book.cakephp.org/complete/1143/Data-Validation#Adding-your-own-Validation-Methods-1181 on how to add my own validation methods, but maybe I'm missing something.

I only want to validate that Field_B is 'numeric' (a core validation) if Field_A (a select/option) is equal to a certain value.

It seems that I'm supposed to add a custom validation, and then I check the values of other fields with $this->data, but how do I call on a built-in validation from within a custom validation function? Or am I doing it wrong?

    Validation::numeric($this->data['field'])

    Validation class (validation.php) is located in cake/cake/libs and you can see the available methods by inspecting the file (they're the same as the ones you pass to the validation array).

    Validation methods return true if validation passes.
