So, thanks to the pointer by @PeterHahndorf I discovered that indeed, the type of pass and the number of days allowed is all written in pen on the entry stamp.
Without deliberate inspection I'd missed it on both stamps because the '90' was written very quickly and wasn't immediately recognisable as a number!
What confirms it is that on both stamps, the pass type of PIP 5 is also ticked. PIP followed by 9 boxes is printed on the stamp, along with a visa type line below, where the immigration officer will indicate the pass/visa type in pen.
Once I knew what to google for I confirmed that that PIP 5 is indeed a 90 day pass on the migracion Colombia site.
So, I have to presume I do have 90 days from the date of the latest stamp. I'll update this if I discover differently.

I would think that both your passport stamps include a reference as to how long you're allowed to stay.
CIBT (http://cibtvisas.com) claims that British passport holders get 180 visas upon arrival. You might have gotten 90 days that could have been extended by another 90.
This should mean that, leaving earlier and returning, it's most likely that you were given another 90 days from your second entry.
However, because the number of days you get is at the discretion of the immigration official, if the number of days you got is not specified with your stamp, there is no way to determine, without checking with immigration, how long you're actually allowed to stay.
