    **Examples:**

    List the suitable scripts for the language “Serbian”:

    >>> list_scripts(languageId="sr")
    ['Cyrl', 'Latn']

    So this returns a list of scripts which are in use for
    Serbian. These lists are sorted in order of decreasing likelyhood,
    i.e. the most common value comes first.

    List the suitable scripts for the language “Punjabi”:

    >>> list_scripts(languageId="pa")
    ['Guru', 'Arab']

    One can also list the possible scripts for a territory like
    “Pakistan”:

    >>> list_scripts(territoryId="PK")
    ['Arab']

    If one knows both, the language “Punjabi” and the territory
    “Pakistan” or “India”, one can find out which script is the
    preferred one:

    >>> list_scripts(languageId="pa", territoryId="PK")
    ['Arab']

    So the preferred script for Punjabi in Pakistan is “Arab”

    >>> list_scripts(languageId="pa", territoryId="IN")
    ['Guru', 'Arab']

    and the preferred script for Punjabi in India is “Guru”.
