I simply need to add a validation class that limits a numerical entry from being greater than 24.
Is this possible with CI's default validation classes or will I have to write a custom validation class?

You can use validation rule "greater_than[24]"
like for Example
$this->form_validation->set_rules('your_number_field', 'Your Number', 'numeric|required|greater_than[24]');

There's no maximum or minimum comparison function in the Form Validation Rule Reference, so you can just write your own validation function.
It's pretty straightforward. Something like this should work:
function maximumCheck($num)
{
if ($num > 24)
{
$this->form_validation->set_message(
'your_number_field',
'The %s field must be less than 24'
);
return FALSE;
}
else
{
return TRUE;
}
}
$this->form_validation->set_rules(
'your_number_field', 'Your Number', 'callback_maximumCheck'
);

Sure you can, just make your own validation function and add it as a callback to validation rule. See http://codeigniter.com/user_guide/libraries/form_validation.html#callbacks
Hence, you will have
...
$this->form_validation->set_rules('mynumber', 'This field', 'callback_numcheck');
....
function numcheck($in) {
if (intval($in) > 24) {
$this->form_validation->set_message('numcheck', 'Larger than 24');
return FALSE;
} else {
return TRUE;
}
}
