Items not in Numerical Order

[lecotillon]

My items were in numerical order, now they aren't anymore.

 

I've checked my product attributes, but I'm not seeing where it is that I can change the sorting values.

 

Can anyone help me out?

 

If you need an idea of what I mean... www dot lecotillon dot com//catalog

 

The aero knitting needles, check out the circular ones.

 

The sizes aren't in order from smallest to largest, they're listed randomly it seems. They list random when I enter them too.

 

Thanks in advance.
