Issue
Your script requires a PHP version other than the latest PHP version. Even after changing the PHP version with the PHP Version Selector your cron still runs with the native PHP version (typically the latest).
Solution
Replace /usr/bin/php
with the appropriate PHP version below:
/opt/alt/php44/usr/bin/php
/opt/alt/php51/usr/bin/php
/opt/alt/php52/usr/bin/php
/opt/alt/php53/usr/bin/php
/opt/alt/php54/usr/bin/php
/opt/alt/php55/usr/bin/php
/opt/alt/php56/usr/bin/php
/opt/alt/php70/usr/bin/php
/opt/alt/php71/usr/bin/php
/opt/alt/php72/usr/bin/php
/opt/alt/php73/usr/bin/php
/opt/alt/php74/usr/bin/php
/opt/alt/php80/usr/bin/php
/opt/alt/php81/usr/bin/php
/opt/alt/php82/usr/bin/php
