For example, [...] Although there isn't an XPath 1.0 operator for string comparison, XSLT 1.0 still has to be able to compare strings because of <xsl:sort>. So you could apply-templates or for-each on the list, using <xsl:sort> to sort alphabetically, and then flag any element where its position() != count(preceding-sibling::*) + 1. I'm not certain that it's any prettier. Because you are using apply-templates/for-each (which conceptually does its items in parallel), you can't stop after flagging the first out-of-order item. You are also at the mercy of your locale as to what "alphabetical order" is. That may or may not matter to you.
