Change the middle number in the 'splice' to select an alternative column (minus one, if you think one-relative).

If you wan to parameterize, and make the selected column one-relative, you could do this: 

perl -sane 'print  join ("\t",splice(@F, $COL-1 ,1),@F ), "\n"' -- -CO
+L=2  YourFileName.txt

Note that you need the "--" to separate 'perl' options from program options.

or - this option that uses fewer keystrokes and space-separated columns: 

perl -sape '$_=splice(@F, $COL-1,1)." @F\n"' -- -COL=3 YourFileName.tx
+t
