Description

Experiencing the same issue that Checkov throws on dynamic NACL blocks with rule_no of non integer (or integer + variable).
The fix is maintiang the sort similar to how it was suggested by the maintainer in the issue, perform relevant checks and uses force_int() to get the rule_no and otherwise, push the dynamic values to the end of the order.

Fixes #5893
