Hola @Robert_Petitto and @JackVaughan
Very weird the situation, I tested that plugin days ago and worked perfectly using a Number or Text column, it was even very smart by sorting the array.
Today I retested it and it still works perfectly!.
Here my result when my Num column is Number type
and here when my Num column is Text type. The plugin was very smart to recognize that all text values were numbers and could sort it perfect. Otherwise, the sequence would have been different (what Robert has).
Regarding the sorting an array of dates, this is true, the plugin fails. Here I wrote an advise to David about this issue:
