As the documentation explains,
selected-at(${PER68}, 0) should give you the “first” selected element (name) related to the choice item list (NOT related to the order of the select in the UI). ${PER68} provides all elements (but unfortunately for your demand) in automatically selected order, separated by one blank/space. The automatic ordering is based on the line order of the choice items in the choice_list.
Another option, showing the labels, was explained by Kal_Lam https://community.kobotoolbox.org/t/how-do-i-display-the-responses-in-a-note-that-i-made-for-a-multiple-response-question/6983/13.
There you also find other examples for showing the selects as a note or a read-only list

As we can see with a form download from 2021-01-16, this automatic re-ordering was introduced later with a KoBo update! Maybe @jnm or @josh or @Kal_Lam can explain more, and give a hint to any documentation. As far as we can see, before the responses (in the table view and in the XLSX download) were stored in the order of the select on UI level. Here an example
I think, this change helps for analysis (normally), but now there seems to be no more stored information about the sequence of the choices on UI level. Sorry, if we missed something here: We would appreciate that such changes are documented and communicated to the community, please.
