To use

cscript //nologo script.vbs sort {n|d|t|tt} {a|d} startcolumn  endcolumn < input.txt > output.txt

Options

n - extracts a number from the columns specified. Looks for the first number.
d - extracts a time or date from the columns specified. Looks for the first date.
t - extracts a text string including spaces from the columns specified.
tt - extracts a text string discarding leading and trailing spaces from the columns specified.
a - sorts acending
d - sorts decending
startcolumn - the starting column, the first character is column 1
endcolumn - the ending column
