Change frame rate of a Sequence

Hello again!

Would like to know: is it possible to change frame rate of a Sequence via scripting?

I need to set a custom number of frames. If I understand it correctly the choice is limited by the timedisplay table from the guide (100 TIMEDISPLAY_24Timecode, 101 TIMEDISPLAY_25Timecode, etc). But may be i need a 100 fps or 120?

Thank you!
