The trick (and the inconsistency) is that multiple positions create multiple TEXT objects and only one single SYMBOL object.
The correct way seems to be (note the 'foreach' line):

cols = ['BLUE', 'PURPLE', 'RED', 'ORANGE']
p2 = plot(INDGEN(10))
p2t = text([0.3,0.3,0.3, 0.3],[0.8,0.77,0.72,0.69], cols)
foreach t,p2t,i do t.FONT_COLOR=cols[i]
p2s = symbol([0.27,0.27,0.27, 0.27],[0.8,0.77,0.72,0.69], 'circle', SYM_COLOR=cols, SYM_FILLED=1)

You get the same inconsistency if you jointly use LABEL_STRING and LABEL_COLOR keywords in SYMBOL (in order to avoid the TEXT calling).
