Is there a way I can display a running total of points earned across the whole experiment either in a feedback trial or in a <page> at the end of a block?
Thanks!

Yes. Suppose you have store the total in values.totalpoints. To display it in a <text> element via a <trial> do:
<text youtotalpoints>
/ items = ("You have achieved <%values.totalpoints%> points! Congratulations!")
...
</text>
<trial feedbacktrial>
/ stimulusframes = [1=yourtotalpoints]
...
</trial>
If you want the total to be displayed in all your trials, add the yourtotalpoints stimulus to those trial's /stimulustimes or -frames.
Displaying it in an instruction <page> works the same:
<page feedbackpage>
You have achieved <%values.totalpoints%> points. Congratulations!
</page>
<block someblock>
/ postinstructions = (feedbackpage)
...
</block>
