This is the way I found best to work a twist over 3 stitches.

Instructions
Twist-3-Right: slip 3 stitches as if to knit-3-together, return all 3 stitches to left needle, k these stitches one at a time through the back loop.
Twist-3-Left: slip 3 stitches one at a time as if to knit, return all 3 stitches to left needle, slip these 3 stitches as if to purl-3-together through the back loop, knit these stitches one at a time normally (or through the front loop).
