It doesn't matter what you do. Some will always read them in a different order. The brand should include use of the company name in some locations so that, eventually, the public gets used to thinking H-- S--- S--- C---. As you can see HERE the order is largely irrelevant and makes no sense until the actual name of the company is included.
I, personally, read it as HCSS - but that means very little. My (English speaking) brain tells me to read from top to bottom, left to right, After all that's how we are taught to read - so H-CS-S. I would never think to read in a clockwise fashion, even if you rotated the characters (which I actually think is a horrible idea).
Even when reading an actual analog clock, the eyes don't track the numbers in a rotational fashion. The natural order is to see the 11-12-1 combination, then the 8-9-10 combination, then the 2-3-4 combination, and lastly the 5-6-7 combination and track while reading in that order for items (hands) in those areas. So, even when things actually are clockwise, the natural order is not to actually read clockwise (in an English speaking country).
No logo starts as just a symbol -- Apple, Nike, AT&T, Ma Bell, etc.. all start with a symbol and name, until the symbol is recognizable enough that the name can be dropped.
