So, @row = ((0) x 361); is creating a one-element list whose element is a scalar string of 361 zeros.('0000000000000000 ... 00000')

No. 0 x 361 would do that. (0) x 361 creates a list of 361 zeroes. 

>perl -E"say for (0) x 5;"
0
0
0
0
0

>perl -E"say for 0 x 5;"
00000

Yeah, that's a pretty quirky syntax.
