When I tried your script on Windows XP using GNU Awk 3.1.3, I found
this error:

gawk: cmd. line:1: 'ORS=1?,:\t'
gawk: cmd. line:1: ^ invalid char ''' in expression

If that is the problem you encountered, you have to escape the double-
quote mark in a double-quoted string using the "^" (double-quote caret
double-quote) sequence.  (It's as awkward as it sounds.)

Try:

gawk "ORS=1?"^"","^"":"^""\t"^""" %1.tsv > %1.csv
