Sort dimension that has integer and alphanumeric values

[cloud]

hi, 

I have a 'no. of month' dimension. it has values ranging from integers to alphanumeric eg. 5,1,7,6, < 1 Month

How do I sort such that '7' is at the top, descending all the way till '1' and '< 1 Month' is at the bottom below '1' 

any help is appreciated! thanks.

hi claudiu,

I'm looking for an dynamic expression instead of static input. thank you.
