Rather than 

number(substring(A,B,C) - 1000)

you need to write

number(substring(A,B,C)) - 1000

Generally, XPath 2.0 is stricter about type checking than 1.0 (though if you
specify version="1.0" in the xsl:stylesheet element then most things revert
to the 1.0 rules). If you want to use a string as an arithmetic operand, you
now have to convert it to a number explicitly. This change allows operators
to be overloaded to do different things with different data types.
