How are you actually calling your extension function? I don't think your examples show that (unless using <my:LineWeight> is some way to call an extension function that I'm not familiar with).

Because <my:lineWeight> is not using the XSL namespace, the XSLT processor thinks it is just an element that is to be copied to the output. Therefore the value of your select attribute is just the string "exslt:node-set($def)/bo/totals", and that is what your extension function is receiving. Try using <my:lineWeight select="{exslt:node-set($def)/bo/totals}" /> in your XSLT code, which will tell the processor to evaluate the expression (note the curly braces).
