Your solution could be rewritten
fold-left($x, (), function($a, $b) {$a, ($a[last()], 0)[1] + $b})
I can confirm that, above expression evaluates correctly.
But why does the following doesn't give the correct answer ?
<xsl:variable name="inpValues" select="(1,2,3,4)" as="xs:integer*"/>
fold-left($inpValues, (), function($a, $b) {$a, $a[last()] + $b})
i.e why can't $a[last()] work instead your's ($a[last()], 0)[1] ?
