Problem: I would like to use a custom function in a conditional, but I cannot get it to work as expected.

Solution: In this case it is possible to create a custom shortcode instead of a function that adds a filter and returns some result. See the below format for creating a custom shortcode that returns some value, then register the shortcode name in Toolset > Settings > Frontend Content > 3rd-party shortcode arguments.

function paid_memebers_filter() {
  $value = 'notpaid';
  // ... your code should modify $value here if necessary...
  return $value;
}
add_shortcode( 'paidviewfilter', 'paid_memebers_filter' );

Then you can use it in a conditional like so:

[wpv-conditional if="( '[paidviewfilter][/paidviewfilter]' eq 'paid' )"]
...paid content...
[/wpv-conditional]
[wpv-conditional if="( '[paidviewfilter][/paidviewfilter]' eq 'notpaid' )"]
...unpaid content...
[/wpv-conditional]
