The list-sod-policies | SailPoint Developer Community API supports the standard sorters collection parameter, but the documentation does not mention this.
When visiting the Search > Policies page in the UI, the browser makes the following request to this API: /beta/sod-policies?limit=50&offset=0&count=true&sorters=name. Through testing, it also supports sorting on created and id as well. I have not tried any other fields, though.
Additionally, some SOD Policies APIs are grouped under the SOD Policies tag, while others are grouped under a separate SOD Policy tag with no landing page (e.g. start-sod-all-policies-for-org | SailPoint Developer Community )
