No problem! You also have a label repeated, which makes the first item to select the second radio-button:

    <input type="radio" id="factor-weight-4" name="score" value="4">
    <label for="factor-weight-3">super important</label>
    <br>
    <input type="radio" id="factor-weight-3" name="score" value="3">
    <label for="factor-weight-3">pretty important</label>

great catch -- fixed now, thank you!

It'd also be nice if after submitting for one and selecting enter that it autofocuses on the input for the next question so you can start typing without clicking on it.

this has been fixed :D thanks!
