If they include this poll, he'll need to poll 3% in another.
Based on RCP, if there is another poll Rand's then most recent three results will be 4, 2, and 2. In that case, I think he'll only need 2% to make the debate, not 3%. If more than one poll comes out, though, that 4% from CBS will get bumped and he'll need 3% in each of the next two polls. Since they are only using four polls, there is still a lot of uncertainty.
Someone please correct me if my math is wrong, but I believe at the moment:
Rand qualifies; he needs at least 2% in the next poll to maintain
Huck qualifies; he needs at least 2% in the next poll to maintain
Kasich qualifies; he needs at least 2% in the next poll to maintain
Fiorina qualifies; she qaulifies regardless of the next poll, but two polls will wipe out the CBS 7% and put her on the bubble
Christie qualifies for the undercard; he needs at least 5% in the next poll to qualify for the main debate
Are the requirements for the undercard 1% in at least one poll, or a 1% average? If the former, the rest are in the undercard right now. If the latter:
Graham does not qualify; he needs at least 2% in the next poll to qualify for the undercard
Jindal does not qualify; he needs at least 2% in the next poll to qualify for the undercard
Santorum does not qualify; he needs at least 2% in the next poll to qualify for the undercard
Pataki does not qualify; he needs 4% in the next poll to qualify for the undercard
