using 'state' requires 5.10.0
Improved the fix for RT#95023

The regex

    qr/^5\.01301/

would have matched some version numbers that
should signify a fail, so changed it to

    qr/^5\.013010?$/

Which more accurately specifies what we're after.
"use base 'Exporter'" shouldn't require 5.008+ -- RT#89173
