I need a small AVR and the ATTiny20 seems to fit the bill (Normally I use ATMega48/88/..). However, unless I'm missing something, the '20 does not seem to use the standard ISP interface, but uses only 3 pins (RESET, TPICLK, TPIDATA). Will a normal ISP programmer e.g. STK-500 program these parts? If so, what is the wiring to the 6-pin ISP header?

You need a STK600 or an AVRISP-2.
The STK500 can NOT do TPI.
You can see the 6-pin pinout from the regular Atmel docs.

An USBASP can do TPI if you upgrade the firmware. Note that the default USBASP firmware uses a slightly different pinout to the AVRISP-2 / STK600.
