Probably he meant $sort contains a string and not a number.
In that case $sort would be converted to a number and evaluated to NaN
(assuming this special string can't be converted to a number).
According to http://www.w3.org/TR/xpath#function-substring
(particularly the 4th example) I would expect that the result of this
substring call is "".
If $sort *is* declared somehow then the processor mustn't report an error.
Cheers,
Oliver
