Hmm, ok. I got confused by the 'tab-bar-select-tab-modifiers'
docstring, which says

    List of modifier keys for selecting tab-bar tabs by their numbers.
    Possible modifier keys are `control', `meta', `shift', `hyper', `super' and
    `alt'.  Pressing one of the modifiers in the list and a digit selects
    the tab whose number equals the digit.  Negative numbers count from
    the end of the tab bar.  The digit 9 selects the last (rightmost) tab.
    For easier selection of tabs by their numbers, consider customizing
    `tab-bar-tab-hints', which will show tab numbers alongside the tab name.

Perhaps the option of doing C-u <digit> <MODIFIER>-9 should be
mentioned there as well?
