I am reading multiple ADC channels on an STM32F0 using DMA. I am reading the data into an array. The data does not appear in the array in the order of ADC channel number. It is my understanding that the F0 does not permit reordering the sequence of ADC channels. What sequence do the 16 channels follow?

has said it all.STM32F0 and STM32L0 series have the specificity of ADC sequencer order fixed: order of sequencer ranksis defined by channels number.
On other STM32 series, ADC sequencer is flexible: you can specify what channel mapped into sequencer rank1, rank2, ...
You have to pick the each channel ADC conversion data to the corresponding DMA destination buffer index.
In the case of STM32F0, you can find some examples in STM32F0 FW package (can be downloaded here:
