this playbook shows an example of int test and use a block/rescue:

- hosts: localhost
  gather_facts: false

  tasks:
    - block:
      - name: disk usage from command module
        shell: df -h / | tail -n 1 | awk '{ print $5 }'
        register: used_space
        failed_when: used_space.stdout | replace('%', '')|int < 70

      - debug:
          msg: "space = {{used_space.stdout | replace('%', '')|int }}"
      rescue:
      - debug:
          msg: "do what you want"

if a task is failed inside block, you are using rescue task
