I believe AutoSPInstaller has been ammended to correct this port specification issue are you using v3.87 of AutoSPInstaller?
I changed the Auto SPInstaller code to work around the restriction as follows:
$objSQLConnection.ConnectionString = "Server=$sqlServer,1433;Integrated Security=SSPI;"
My fix is to add a new element in the config.xml <DBServerPort>1433</DBServerPort>.
