tswor with a strong puff of air, dropping hard. The c is an aspirated "ts", not an English k or s.
cuò
The fall is fixed, and it triggers the negator: 不错 becomes bú cuò, an extremely common phrase meaning "not bad". That expression is worth learning as a whole unit precisely because the rising bú in it looks wrong to anyone who has only memorised the citation tone of 不.

这个号码错了。 places cuò before the toneless le, so the fall is followed by a weightless tail at the low pitch. Ahead of it, hàomǎ pairs a falling tone with a dipping one, and no sandhi applies since they are not both third tones. The sentence therefore drops, fades, drops, dips, drops, fades — heavily weighted toward the bottom of the range.
Reading c as English "k" or "s" produces kuò or suǒ, neither of which is the word. It must start with an audible "ts" as at the end of "cats". Under-aspirating instead gives zuò, which is a real and very common word, so the puff of air is genuinely load-bearing here. And -uo routinely flattens to "oh", losing the rounded onset.
