I was replacing some drywall and noticed the wiring underneath has a couple of surface tears. House is from the sixties, but has been rewired with new Romex, except this circuit. Wire seems to be old type of Romex (cloth covered) and has the marking "HATFLEX NM 14/2". Only the cloth is partially teared-up.

Should I be worried about this? I was considering putting some electrical tape over the damaged sections. Is this ok? What other alternatives do I have?

Repair

You can use a cable jacket repair tape, to repair the jacket. I would not use simple electrical tape to make the repair, since it has a tendency to dry out and fall off.

Repairing Damaged Cable Jacket When No Portion of Cable Jacket is Missing

  • Abrade the cable jacket 3" (75 mm) beyond each side of the damaged cable jacket section

  • Wrap one half-lapped layer of Scotch® Cable Jacket Repair Tape 2234 extending at least 2" (50 mm) on each side beyond the damaged cable jacket

  • Starting 1" (25 mm) past the Scotch® Cable Jacket Repair Tape 2234, apply 3 half-lapped layers of Scotch™ Super 33+™ Vinyl Electrical Tape to each end to temporarily secure the ends of the Scotch® 2234 tape to the cable jacket until the tape reaches full bond. figure 3

If the section is accessible at both ends, you could simply replace the section of cable.
