data-sort-value clearing 0 values

[teamayu]

I`m using data-sort-value for integers and prices, but any value of 0 or 0.00 is being cleared, resulting in:

data-sort-value=""

This means that price lists that contain 0.00 don`t sort properly.

Superb plugin btw, thank you.

Apologies, ignore, this was me being stupid. :(
