Sorting is working only in configured containers, the configuration is stored in file etc/view.xml.
Default enabled containers:

<vars module="MageSuite_ProductDetailsReorder">
    <var name="sortable_containers">
        <var name="0">product.info.details</var>
        <var name="1">product.info.details.main</var>
    </var>
</vars>

To sort blocks inside containers new argument needs to be added:
<argument name="sort_order" xsi:type="string">120</argument>
argument with If this is not specified then the default sort_order name can be used in order to sort child blocks inside product.info.details and product.info.details.main blocks. is 10.

Example:

<referenceBlock name="product.attributes" group="column_right">
    <arguments>
        <argument name="contain_content" xsi:type="boolean">false</argument>
        <argument name="sort_order" xsi:type="string">20</argument>
    </arguments>
</referenceBlock>
