Don't leave the avi 60fps, it does be wrong. In fact its framerate is the same as input, so please use "change frame rate". I use aviread because I want to avoid it becomes 60fps or 120fps. I know.

Tc2cfr (by tritical) or avitmux (by Aji) can insert Drop-frames into AVI with timecode file. (avitmux supports only v2) Yes, AVIRead is very nice and precise VFR tool for imitative-VFR (such as 120 fps/60 fps AVI) which can do manual IVTC easily with TMPGEnc. Moreover, AVIRead can insert Drop-frames into Video, and mux it and audio into AVI at the same time. (I don't know any application that can do it.) Though the followings are not what you intend, I try to adapt tc2asc to timecode files which AVIRead and TCGenedit (my VFR tool imitating seeking IVTC pattern of AVIRead) generates from a TMPGEnc project file, and tc2asc extracts AVI Scripts. I open the script and video, and output 60 fps AVI container with AVIRead. The AVI has the wrong timing frames. AVI generated from ASC using TMPGEnc project file with AVIRead has right timimg frames. Why does this happen? Because AVIRead doesn't recognize '0' until the first '1' comes. For example, "0000100000" is identified with "1000000000" in AVIRead, and the timing of the frame will shift from the original. This is fatal on deduplication.

Because AVIRead doesn’t recognize ‘0′ until the first ‘1′ comes.
For example, “0000100000″ is identified with “1000000000″ in AVIRead, and the timing of the frame will shift from the original.
This is fatal on deduplication.
